You could have used tie wire to tie the rebar together and to secure the conduit. You also need a bushing on the end of the emt to protect your electrical cable from damage. One suggestion: can you try a design where you use the rope light in place of some of the bars of rebar? I think that might make for an interesting look.
To give your concrete more of an authentic look instead of using melamine use pieces of a plywood as they would leave slate imperfections of the plywood in the veneer of the concrete giving it a more realistic look
Version 3 has my preference. But damn, this is a cool concept. As for RGB and white, you really should want one that has both RGB and separate dedicated white LEDs for best result.
Something to consider when it comes to rigging standards for overhead installations. Where I work we almost always use a combination of brass inserts with 1/4 20 steel shouldered eyebolts with quick links rated to exceed your maximum hanging weight. These are not only much more secure than two screwed in hooks, but with primary and secondary connection points (4 separate inserted shouldered eye bolts) in the case of say an earthquake or something hanging or catching on the installation you can be confident the connection points will not fail and potentially fall on someone, avoiding injuries and or property damage.
Two things - I’ve been a long time viewer and it’s super cool to have watched you experimenting with GFRC before anyone else, working with LEDs, working on years of projects on your building - this piece feels like it’s the culmination of years of working with all those different mediums with a great result. ALSO, very cool - I’ve followed lukelampco for a while and have always been in awe of his light sculptures - and this is a great project to make it more accessible. Great work.
So funny you posted this today - I just took delivery TODAY of a meter of this LED rope randomly discovering it a couple of weeks back. I love this new led strip format and can't wait to play with it - will definitely be ordering some more. I think it might be fun for creating "neon" style signs!
For a more clean look. You should looking a Nico press with the copper sleeves. Instead of the (Crosby) you called them saddle clamps. It’s 100% cleaner. Also just a warning wire rope bought at a hardware store is not rated for overhead lifting. It will work but there is some danger in it about 10% . Love your content been watching it for years @modustrial.
Actually, you could have all of them and periodically change the alignment of it whenever you get tired of it. It can be always changed, so that your visitors will be baffled when they come over and eat at your place. They will wonder why it looks different. Depending on how that LED rope connector is, maybe switching it out with different light hues or colors if they have them. It might be interesting when large get togethers of mood lighting. Good video. I enjoy watching the creativity and fun, you get making your vision come to life. Who knew as a adult, one gets to play with sand construction and make a living from it.
Man.. i remember watching the urban decay lamp video a year or 2 ago.. time really do fly.. RIP Karma cat.. its good to see the bulb is still shining bright.. my eyes are sweating a little 😭
As a beginner interior architect, I would absolutely go with the third option. With the rope spread out all across the entire beam, you'll be able to light up a larger surface area in comparison to the other two designs. The design itself is also calmer and more elegant than the other two, it fits your interior better in my opinion. The concrete ends are also truly incorporated into the light now.
Loved Lukelamp forever. I've tried making these myself using marine rope sheeting. They definitely did not look as perfectly diffused as the store-bought version. I also can't get enough of this style of lighting.
Not shown in this video...the basket full of tubes, sheathing, cable cover, etc I bought trying to recreate it before I found the pre-made one. Probably spent a $1000 on products i didn't use... it was a journey.
I like option 3 best, but it looks a bit unbalanced to me. It may look better if the left side also looped over the end of the block like right side does. Love the way it looks
Option 3!!! I used to watch you religiously during Covid but somehow got out of the habit? So glad this video popped up on my timeline and brought you back to me. YAY love this
I like Option 2. But if you had a little more length to play with, I think Option 3 could look better. As #3 is now, I think the LED rope is too spaced out and just going from point A to point B, hence why I think having a little more length could take it up a notch. Honestly, any of them would be great. Overall great project and I love the look.
I like 3 but 2 is my favorite, and if you had a longer piece I would just do 2 but bigger to incorporate the concrete ends. I just love how it really did look like a bulb filament! I love randomness and “urban decay” look but I also really love when something simple visually rhymes with something very familiar… so even if you don’t recognize it at first, your eye goes “hey that’s really familiar… I’ve seen that before… but where?” and then halfway through dinner it clicks and you go “Oh damn! It’s a lightbulb!” Hahaha That’s my reason for choosing 2 as my favorite, but I do agree about including the concrete. Like I said, a longer rope would allow the best of both!
BRO WHY DID YT STOP RECOMMENDING YOU. I watch you all the time (Or used to) and one day you jus stopped showing up, until now. So now im going back to watch everything I missed
I like 3 the best for keeping the "rope" aspect of it. I think the way I'd do it though is to have a straight piece of the rope going from one end to the other, sort of like a tube of light in the middle. Not that it matters at all in this sort of application but in a structural application you're not "supposed" to weld rebar. Reason being is that common rebar isn't actually isn't that weldable, the welds can be prone to cracking. Also, if you in a situation where it has to be inspected, most inspectors aren't qualified/equipped to inspect welds.
Go with Option 3 man! Love all that urban decay art you are doing. That LED lighting looks really fun! Great work and always look forward to your content.
Option 3 is the best but I would put the string of light on the left side of the fixture to be on the other side or at least go through the cable, just to have a little bit of symmetry 👍👍
My vote would be for option two, i like the semi separation going Concrete - Light - Concrete, it kind of gives it the feel of the lights having broken free from the concrete. That is just what i prefer though and you should go with what you like the most!
Cool light fixture. Liked the Third best- almost wich you had three more ft of light rope. Or hidden uplights in the top of the concrete to cast some slightly different colored light on to the ceiling.
Option 3, because the whole lamp looks as 1 piece while Option 2 it feels the light element not fully integrated in the concrete elements. Fantastic job!
Purely on shape I think option 2 is the most pleasing, because of that filament kind of vibe you mentioned. But since it needs to be functional as well as pretty it seems like option 3 is the best choice balanced between nice loops and wide light distribution. The best thing about this structure though is that you don't really have to settle on one single configuration. If you get tired of it you can always climb back up there and rearrange it again. It's always new and exciting :) Glad to see a video from you again. Your projects are always fun to watch. I noticed doggo has a cone on in this vid, I hope he is ok.
Option 3 is the best choice, spreads out the design and the light and gives more to look at. I was thinking how would it look if you went back over the top of the concrete and then wrap around the centre and wrap around the concrete on the other side, could look cool
Option 3 as it lights up the concrete and draws your sight to the work. Also, still enjoy the caulk talk! 😛 Found a place near by who does GFRC training courses so I'm planning on doing that sometime next year! Purely based on inspiration from you.
That's awesome! I'm also thinking of doing a thorough online course for concrete/GFRC... Curious if that is something that would interest you? (And feel free to answer either way... I'm currently just gauging interest to decide whether or not it's worth doing)
@@modustrial I'd be keen as the information from you would be on point for the hobby! Having that useful tips, tricks and failures that you've experienced along the way in a single spot would be great.
Definatley option 3. Work on it some more. Maybe extend it even more off the ends? Such a cool project. Gets the imagination going like, next version, adding fiber optic filaments to look like sparks coming out of the concrete around the LED cable ends.
Also, don't use those hooks. Use forged eyebolts. I worked for an audio video company years ago and they were brought in to repair the speaker mounts in a large church. The original mounts (by another company) used those hooks. The were rated for the weight, but over time, the hooks deformed. Drop forged eyebolts will never deform.
i like 3 the best but worry it'll slip off the concrete on the left side. Across the concrete is the way to go though! Cant wait to see more, keep it up!
I LOVE option 2 but I also see why 3 is the most practical. I propose option 4, a longer light or second light that then creates a combination of options 2 & 3.
Option 3 looks the best with the structure that you have currently. However my favorite design is options 2. As you said it needs to be longer and more spread over the table in the space. Clearly you need to build a second one that is much longer so that you can go with option 2 and still have it illuminate the space well.
When connecting two different types of metals in a possible moist environment,electrically isolate the two metals from each other with either electrical tape or heat shrink tubing. This will help minimize galvanic corrosion.
I liked option 3 but it could be super cool to start the first loop going back over the concrete and in between the cables before looping around. It would light more of the table and look cool to have it circle around the outside end of each concrete block.
Long time no see, hope you're doing well Mike! My vote is 100% option 2. Just like you said, the spiral effect reminds me of edison light bulb, I think it's so cool!
11:29 I wonder if you could “glue & heat-shrink” the cables and thimbles… the connect the ends with a steel cable crimp as well as heat shrink those… (to reduce the size and bulk of the saddle clamps)…. Them you can use a turnbuckle for final adjustment to keep each end level (possibly media blast the sink coating off and paint to match the hear-shrink) This is an amazing project… also would “aircrete” be too crumbly for the project?… coat the outside of the project with glass reinforcement HIGH STRENGTH concrete on the bottom and sides (troweled), fill mostly with either aircrete or a concrete with shredded styrofoam “beads” (like that’s in a bean bag chair) to lighten up the concrete…. And finished with the top being the final layer of high strength reinforced concrete. (I was going to suggest expanding foam but there would only be two ways to do it and one concern: 1. Use high strength concrete or grout on sides and bottom (or exposed sides) let set, fill with expanding foam then put the high strength concrete over the exposed foam. 2 place “support foam” as you add the high strength concrete, then once set, fill the cavity with expanding foam. …but then there would be a seam, and depending on the foam, possible breakdown over years) Love the content though! Too bad it’s most likely impossible to “tie knots” in the rope light without damaging the led’s.
Am I the only one who would’ve liked to see a couple of LED rod lights through the copper in the concrete? Since he’s going with the LED rope, light look, I think that option too visually fit the style better.
Option 2 for me it gave it a sort of halogen tube bulb look with the filament in between end caps, doesnt matter anyways it'll look cool in any configuration.
i think either one or two, but i also think a straight light with this warm white would look really good too, like just a straight filament through the centre of the two blocks
Given the three options, I'd say #3 is the best looking by far. Although I'd love to see a take on option 2 that incorporates the concrete ends, and possibly a variant that mimics a DNA spiral, but that's also probably quite a challenge given the fixed length of your lighting elements.

I like Option 3 the best because it incorporates the concrete ends.
3
Think you nailed it with option 3. You're right about the light needing to be long and extending over the concrete, it also really works visually.
I liked option 2! The giant filament is a cool look.
I didn't think I would like it when I saw it at first, but I think 3 is by far the best and it grew on me quite quickly. Great job!
thanks Frank!
Version 3 has my preference. But damn, this is a cool concept. As for RGB and white, you really should want one that has both RGB and separate dedicated white LEDs for best result.
Dubbed "rgbw"
@@Lazaralis And RGBWW if you want them to be warm white
@@Lazaralis there is also rgbww which has both dedicated warm and cool white leds in addition to the rgb ones to allow different color temperatures.
Option 3 is my favorite. I feel it’s the most organic. It has a rhythm to it, like music or poetry.🌸

The jig is up for Luke. I was always shocked by what he charged for such simple work.
Option 3 looked best to me.
You need to paint the clamps & maybe even the wires. I think if you paint them black, they won't stand out as much.

For the emissions comment: concrete is about 1/1 in weight CO2 vs it's own weight. Not too bad on furniture scales, bad on city scales.
yeah that emissions comment was virtue signaling. personal projects like this are going to have a negligible effect

*What's awesome about it is you can always switch it up and change the configuration*
Option 3 suits the length of your table. I was thinking about what I should do with my dining room lights, your video gave me ideas worth exploring!
Option 3!!! Looks Great and Super Cool Project!!
thanks Blake!
Option 2. I like the Edison bulb look. Great video!
Option 2. BTW, congrats on using the saddle clamps correctly! I've seen bridges that 'saddled the dead horse', so major props.
Looks awesome! Option 3 for sure. I'd like to make one myself, but maybe just with a simple wood beam as a base.

Your dog is so devoted in supervizing the work even with the cone of shame 😂
This lamp is so creative. I liked all 3. You can always change it
Option 3, I love the idea of it looping/incorporating the concrete.
Hey I think weldable rebar is painted red on the end, check on that bc regular rebar welds are brittle and can crack.

The add read is fantastic.
I want to try this for my home. Do you have the link to those LED ropes you used on this project?
Option 3, spreading the light out helps highlight all of the build.
Lighting option 3 definitely had the best balance, so that one!
i like 3 the best but worry it'll slip off the concrete on the left side. Across the concrete is the way to go though! Cant wait to see more, keep it up!
You can put rebar together and tie it with some wire or you can fuse steel molten by the power of lightning!
Nice lamp, I'd stick with option 2.
Config 3 is pretty sweet! I'm really impressed with your work here :)
3 is the way to go, it really shows the full construction and uses its space
I LOVE option 2 but I also see why 3 is the most practical. I propose option 4, a longer light or second light that then creates a combination of options 2 & 3.
You gained a follower because of attitude and personality the video taught a lot thanks

I like how spread out option 3 is, good choice!
3, 2, 1 in order of preference. This is great stuff! Thank you.
Nice job. Option 3 looks the best.
I think option #3 is the way to go. Looks the best!
I like # 3. It's larger so it gives more light. Nice job.
I liked option 3 but it could be super cool to start the first loop going back over the concrete and in between the cables before looping around. It would light more of the table and look cool to have it circle around the outside end of each concrete block.
Option 2 looks like a signature to me and i like yhat the most, 3 is the next best as its the most spread out but still looks lt has a good flow
Option 3
Really really dig the idea of a rope light id love to incorporate that into my own home
Long time no see, hope you're doing well Mike! My vote is 100% option 2. Just like you said, the spiral effect reminds me of edison light bulb, I think it's so cool!
11:29 I wonder if you could “glue & heat-shrink” the cables and thimbles… the connect the ends with a steel cable crimp as well as heat shrink those… (to reduce the size and bulk of the saddle clamps)…. Them you can use a turnbuckle for final adjustment to keep each end level (possibly media blast the sink coating off and paint to match the hear-shrink)
This is an amazing project… also would “aircrete” be too crumbly for the project?… coat the outside of the project with glass reinforcement HIGH STRENGTH concrete on the bottom and sides (troweled), fill mostly with either aircrete or a concrete with shredded styrofoam “beads” (like that’s in a bean bag chair) to lighten up the concrete….
