Excellent and very helpful video

Are people so brain-dead that they need a video to figure out the right light color?

Say you have smart lights in your entire house, should they all maintain a consistent color temperature throughout? What are the benefits of this, if any, other than just preference?

Ugh? they look fine. Can you explain the issue?

Best explanation of color temp I have seen, thanks

Thanks for educating me.

which led for my porcelain enclosed overhead kitchen light fixture?

We did all recessed, sconces and fan lights at 40000K and all table and floor lamps at 3000K. It is absolutely the perfect combination. Also, we have the recessed on dimmers and it is even better at night with both the 4000K dimmed all the way down and the lamps on full 3000K. It truly is the best of both worlds and have gotten so many compliments.

Hello there😃 We're fans of your unique style and would love to collaborate with you on a special promotion for your followers. Wanna learn more about the collaboration?

It ain't my preference it ain't my cornea it ain't me getting older, 2700 is fuckin yellow. Yel-low. YELLOW yellow

PSA : high CRI is critical when choosing LED lights. Sometimes you feel you don't like the color temperature when really you're just looking at light from a very cheap, poor LED light. I bought high CRI LEDs in my kitchen, the color is quite cool, but the light is beautiful. Warmer lights are more forgiving when using low CRI / cheap LEDs. The technology has been around for so long now, there's no reason not to buy high CRI. If the box doesn't say the CRI, I'd say don't buy it. High CRI lights will advertise it, and if you buy online, they don't have to be expensive.

Im looking at the 2” downlight the store locator points me to a company that appears to be more suited to commercial applications not really diy guys. Is there an online source for purchasing? I’m looking to see what the price point is on these.

Is there any way to retrofit 6” to 4” by adding an additional rim?

Can I purchase an instrument with adjustable Kelvin light to test with various colors?

Led lights make me crazy. They hurt my eyes and brain. Everything they illuminate looks ugly, no mater the warmth level.

Hello your video on tape light was very informative. Thanks. I've got a two-sided. sort of frosted glass. and it's framed in wood. looking to put lighting. around the back side(which has a 4" reveal) without the glare. It's like 4 feet wide by 5 foot tall. And I liked your idea of excursions. But they would be seen from one side. so my question is what could you suggest? that I could use that would be less of an esthetic thing. Thanks in advance. They call me Tim Tom. And I'm doing this. for my council Knights of Columbus. 3774. Allen Park, MI.

Awesome, m an engineer and interior designer, much helpful, plz keep up the good work. Thanks & regards from India 👍❤🇮🇳

I'd like do the thin 12 volt lighting in my new construction and why didn't they use 12 volt lighting LED

I need lighting for a flat drop ceiling that is only 7-8 inches high. I have considered flat LED but like the recessed lighting look. Do you recommend i use 1'inchers throughout the tiny house build?

These are horrible "other" options. Listening to designers is one of the worst pieces of advice. Get a contractor who is well versed in lighting. If they have accolades or awards in regards to lighting deimsign even better. The products being hocked here are hot garbage. I wouldn't install those in a house if they were given to me free.

It really depends on your style and the color of the surrounding materials (like walls and flooring). I made sure to buy LED wafer lights for my remodel that permit color selection just in case I change my mind. I typically like general lighting to be more neutral in the 3300-3500K range and decorative lights in the 2700-3000K range. It creates an "offset" between the general lighting and decorative lighting removing the flatness all the same color creates. Anything above 3800K is too white and stark looking, unless you have a room full of natural light you want to fill in.

2:06 in india we can't find light bulbs of temprature other than 6500k

If you install these led’s without 0-10v dimming you will need to replace them as often as you’re accustomed to replacing light bulbs. Just don’t do it!

Very helpful. Thank you for sharing. In the kitchen I prefer higher temperature lights so I can see better see for cutting etc.. but yes when you move to living room there is big change which is not best as you suggested. But I don’t see that I have a choice ..

Wow! Marty McFly knows a lot about lighting!

Great job! I sell a lot of linear lights and leaned a few things from this video. Thank you.

I have tried both LED fixtures vs. LED bulbs in traditional cans. I will never use the fixtures again until their cost is the same as a bulb, which of course will never happen. They don't last 22 years and, as others here have noted, when one fixture fails you cannot easily find an identical color light from mostly Chinese manufacturers. Lumens, CRI and spectrum must all be identical because otherwise your replacement light will stand out from all the others that have not been replaced. If you are sensitive to these differences, it is not at all attractive.

Bare lightbulbs have become trendy. You see them hanging in hipster diners. A shade really eats half of the light. The bare flat LEDs work fine shining downwards where you would have had a reflector in the past. In the shade you need a filament bulb with a donut radiation pattern. With more watts it needs the longer base. You can buy a splitter from China, and put two bulbs at an angle. The warm whites peak in the yellow, and some have a pronounced green tint. They don't have anything on the package to indicate this.

In other words, I'm the best.

Wasting time, yet own me 14 minutes

We now have learned all about glare. You shined bright lights right into our eyes! Thanks.

As an electrical contractor with over 40 years of service experience i always worry about getting my hand in the hole for service 4" is good 3" is hard.

Our house was completed in early 2022 with 4” LED down lights used throughout the house. I have a backgrounds in construction and photographic lighting so I worked with the builder on placing them both for aesthetics of the patterns and even coverage per the inverse-square law. In the kitchen, walk in closet and laundry room I wanted 12” x 48” flat panel LED which are adjustable for color temp-3200°, 4000°, 5000°-via flipping the wall switch and wound-up sourcing them myself from Home Depot because the electrical supplier the builder used couldn’t seem to find them. 🤷🏼‍♂️ I’ve had two of the 4” lights fail already. When the first one failed I found and bought six identical spares for <$10 ea. That is something builders using these types of fixtures should do-supply a dozen spares and show the home owner how to change them so a burnt out bulb doesn’t wind up requiring a $200+ and two trips by and electrician to change. Thankfully since no twisting of the bulb is required it now only takes one electrician, not the two additional to turn the ladder. 😂

2700K is my favorite

What about vaulted ceilings with slopes up to 45 degrees? How does the trim mount flush to the ceiling while the light still points down? What is the the beam spread angle? What are the available color temps? What will the replacement availability look like in a few years when so of these fail?

I would never install 6” so ugly 4” all the way.

If you have a recessed light remodel fixture like a HALO 6" H7RICAT or HALO 5" H5RICAT, and you screw in a wifi bulb with features you like, is there any third party product that would at least let you cap the fixture with a lens? That would help to 1) diffuse the light; 2) hide the ugliness of a bulb inside of a can; and 3) help to airseal the fixture. That could at least partially address your concerns, while still giving us the flexibility to select high-end technology for the bulb, which could then be periodically changed out for better technology.

LED lights are awful. They’re way overpriced and only last a fraction of the time printed on the box… and they give people headaches, hurt the eyes… and some studies have shown that LED light grow tumors. Bring back incandescent light bulbs!

I have 6" can lights in most of my house. For those who have a problem with them, there was a movie that addressed this problem called "Don't Look Up". Seriously, I have 9' ceilings so I rarely notice them and if you have higher ceilings, they would be even less noticeable. They put out an excellent amount of light, and it's so simple to replace a bulb that fails. Plus, if you want the same amount of coverage, you need more small lights. Maybe I would like smaller lights if I had them, but I've got no problem with 6" lights.

There is much to consider regarding all types of lighting for residential/commercial use. HEWilliams‬ has an excellent web page. You are scratching the surface; excellent content.

Your HE Williams lights are great until the style changes or you need parts that are no longer available.

Very helpful video. Thanks ❤

You don’t need a retrofit. You can buy LED equivalent flood lights to screw into the light fixture. I added recessed lights in my previous house. I wouldn’t do it today. Times have certainly changed. LED light technology is changing so fast, it makes no sense to add it right now. They’re selling wafer lights. I wonder if they can just do a surface mount in the future.

That shelf is killing me

Okay I watched your video about the recessed cans 6” vs small retrofit. But, there is no way that a 2” or 3” down light is going to cast a wide beam of a 6”. Obviously smaller down lights are more pleasing but the cost you mentioned $100-300 per light hmmn not everyone will be willing to spend that. You can spend more on a good bulb and middle of the road recessed fixture with a good trim and achieve good results. Please comment thanks

Any advice on using vertical tape along bookcase sides to prevent glare and best way to position to maximize lighting?

I am a lighting nerd too. Thank you for making this fantastic video. I look forward to implementing your led color temperature test.

What do you think of Soraa MR16 LED bulbs for recessed fixtures?

Blue light and high Kelvin very bad for you at night!
