126 LED hydroponic death lamp.

  • This fairly common red/blue grow lamp has a rather pleasing array of 126 LEDs arranged as 90 red with a star of 36 blue.
    Hyped power is 15W. Measured power is 5.5W. Actual power dissipated in LED panel is 5W.
    Lamp uses a switching buck regulator that puts out 50V at 100mA and does NOT have an isolated output.
    All solder joints on the front of the PCB should be treated as being at full mains voltage. This doesn't seem like a very good idea for a grow light, as the plants will naturally grow towards the lamp and if a juicy shoot or stem touches any metal, then the whole plant will become live.

    Big Clive, you have a fantastic voice. Your accent and humorous tone are a delightful combination. My father was an electronics engineer and when I was young he bought me simple electronics kits from Tandy and tried to teach me how to solder (an unusual skill to impart to a teenage girl but it has come in useful on occasion!), alas I've forgotten most of what he taught me but your channel makes me feel warmly nostalgic. Thank you!

    A female friend of mine asked me to get her a "plants lamp" for a birthday present and I just searched for that, acquiring a 50ish EUR lamp from a domestic supplier. It came overnight packed just in a plain cardboard box and inside that it was wrapped in a plain clear plastic bag, so there was no much unboxing, and I couldn't help trying it out. I found the hard pink light quite appealing for some reason. So I thought that is what she might have wanted and wrapped it up nice. We had had some incandescent based plant lamps in the 80's when they were "special" and I originally thought this might have an intense white light just as well.
    I dropped it off at her party with some small gizmo I planned for the surprise effect and thought to become useful, including a touch screen glove, USB Micro/C adapter and tablet pen.
    Two days later she called me and asked what the deal about it was. I asked if there was something wrong and she said "no... not really but it's just different than I expected". Turns out we both had had the same expectation. So I explained to her that as far as I know this design is made to take into account the low absorption of green wavelengths in chlorophyll and that the red and blue band together make the light appear magenta or hard pink, and if it had a closely matched green light source in it, it would appear like "TV white", which I oruginally expected as well. And while not being designed to make colorful plants look pretty, it must be a growth improving lamp.
    A week later she called to ask where I had acquired it and how much it cost because two friends of hers had asked her where they could get similar fancy hard pink lamps.

    You could include instructions on how to increase the current, not for me, I know how to probably do that by, I suspect, changing a resistor value. If I were the designer of such lights I would, for 220-240 volts, connect 84 LEDs in series supplied from a SMPS constant current circuit and increase the current to at least 30mA. And of course make it safe to touch when live. Also selling them at the correct power rating :)

    • @topilinkala1594
      @topilinkala1594 ปีที่แล้ว

      That's what I'm saying. To test lamps you should use lumens not watts as the density of light is what you want from lamp to be high and power to be low. So if you compare watts you do not know if low watt lamp gives same lumens as the high watt lamp.

    It's amazing at what gets imported from China now, I recently bought a 240 volt in bridge rectifier. This was supposedly for testing water quality, it has 4 three inch pins which have 240 volt DC output.
    Scary stuff.

    • @GrantE90
      @GrantE90 9 ปีที่แล้ว

      Green Silver As in, a fully packaged product designed to be handled and in contact with water? All the bare bridge rectifiers I buy have 4 terminals for connecting the AC input and DC output (PCB pins and spade terminals are common on the smaller modules, whereas you'll find screw terminals on larger industrial modules). Perhaps they sent you a regular bridge rectifier that's designed to be installed in a circuit, as opposed to a finished water tester. It could even be a replacement bridge rectifier for repairing a water tester (since ebay stores rarely label things correctly).
      Look up the part number on the case. If you find a datasheet for a generic bridge rectifier (and/or it has a hole for mounting), then you have accidentally bought a 4-pin part designed to be bolted to a heatsink and soldered to a circuit board. It's probably due to mislabelling or sending the wrong part.

      Green Silver Whoa, mate, that's extremely shoddy. At first I didn't think any manufacturer was dumb enough to just stuff a BR into a case with a plug, but that's exactly what they've done. Deadly stuff. 230V AC will produce about 325V DC with the appropriate smoothing capacitor on the output, excluding the 0.7 - 2V drops of the diodes. Without any capacitance you will get roughly 230V DC (100 or 120Hz pulsed DC with a peak of 325V). Hopefully they've at least included a resistor and fuse to limit the fire hazard, but it's still insane.

      @kuhrd 8 ปีที่แล้ว +5

      Not sure how this saved you 100+ dollars or prevented a house fire. The 2 main concerns in this video were that the terminals on the front of the unit could become live depending on the type of socket you plug it into (in the US it would likely be less of an issue since the screw of a light socket base is required to be tied to neutral which is also tied to ground) and that they are not really putting out the full brightness. This review was also done over 1.5 years ago and you will likely not find the exact same construction in bulbs you would buy today. The only way you really know is to take one apart.
      One other thing to remember is that you can find LED and compact fluorescent bulbs of dubious build quality even from name brands on the store shelves at your local big box store in some cases.

      Is it that there is no resistance to what the mains is supplying? I assume that the RCD in the consumer unit would trip? Either that or you'd have to rely on the fuse in the plug. So is it DC with mains "power"?

    • @bigclivedotcom
      @bigclivedotcom  9 ปีที่แล้ว +8

      dmak2 Whether the RCD tripped would depend on which part you touched, as although you may get a mains shock it may limit the current enough to cause a severe shock without passing enough current to trip the RCD. That could be very unpleasant.

    Those lamps are not only a waste of money but also a waste of time and more money if you bet a crop on them. You need, at least 1W diodes, being 3 and 5 W the best. 20-25W per square foot would the optimal led lights potency to grow something.
    With this lamps only the leaves on top will get anything, and still, what they get might not be enough. The plant will be very small and/or wither when trying to mature.

    I guess the solution is to put a droplet of glue or silicone in the middle, so the mains connection is not touchable. After the first led the thing isn't really a danger any more.

    @N1H1L9 9 ปีที่แล้ว

    You HAVE done a vid about grow-lights!
    About your electrically live plants, again...mate; perhaps I've lost my fear of 'leccy'. I've stopped a car engine a couple of times with my heart and a moped engine while riding it so I'm less nervous about it than I used to be. I was sticking my hand in a DWC bucket the other day and noticed it felt like peroxide pricking at my skin.
    I was perplexed, as much because I don't bother with peroxide when there's loads of bubbles but also because I'm a little slow sometimes, so I kept doing it until it dawned on me that the pump was shorting out and I was being electrocuted. Maybe I was wearing trainers, I dunno but I really do think sometimes that you'd have to be gripping a lead in each hand to get hurt by the mains. Plant's certainly ain't going to do it unless they're earthing out a thunderstorm.
    I also chopped through a hedge-cutter cable once and discovered that our household breaker circuits are really effective- not so much as a tingle!

    • @bigclivedotcom
      @bigclivedotcom  9 ปีที่แล้ว +2

      N1H1L9 The level of electric shock you get depends on how much current can flow through you. If you were holding grounded metal in one hand and grabbed live metal with the other it would be a very different result from a tingle. I did a video on that. Nobody is immune to electrocution, they just get lucky warning tingles.

      I've never understood 'leccy'; When I was getting all my shocks I was either in trainers or as in the case of my moped shock,
      (dodgy kill switch; the police were coming the opposite way and I was on the pavement, without a bash-hat on an illegal wreck-of-a-ped...I fell off and he just shook his head tiredly as he rolled by!))
      ...I had tyres full of air under me so how did I get any shock?
      I understand an object has 'capacitance' but surely once that's 'full' then no more currant can 'get in'? (sorry, I did warn you I'm like a fluorescent bulb on an icy morning)
      I tell you, the inertia of that tiny ped produced a shock that was easily as strong as the times I've accidentally pulled off a plug-lead or the bloody 'King-lead' (same shock but four times as often!) on a flipping car.
      How on earth, when I can have my hand on a short-circuiting pump under-water and barely feel it (and there was a small quantity of electrolyte in the form of fertiliser), can an engine literally floor me? The HT leads are insulated sillicone- I wasn't stuffing a finger in the end.

    • @bigclivedotcom
      @bigclivedotcom  9 ปีที่แล้ว

      N1H1L9 The chassis of your moped is classed as the vehicles ground. The kill switch may have been breaking the high voltage magneto circuit directly and would give a nasty zing if the insulation was compromised.

      Hi man, how does it ground though? I'd been given to understand that rubber etc was pretty much a brick wall to electricity?
      I'll tell you what though, it wasn't just a 'nasty zing'; it felt like I'd just thrown myself on the fence at Auchwitz. Both the car and the ped were brutal.

    • @bigclivedotcom
      @bigclivedotcom  9 ปีที่แล้ว +1

      N1H1L9 It isn't grounding to earth. It's grounding to the metal chassis of the vehicle which is connected electrically to the negative of the battery. So the high voltage for the spark plugs which is referenced to the battery negative and therefore whole chassis will happily travel through someone in contact with the chassis.

    @oz93666 8 ปีที่แล้ว

    I often wonder how people use these low power grow lights ... plants need about 500W per square meter of growing area ( thats the electrical power delivered to the led's) so a lamp like this gives enough light for an area 10cm by 10cm ... that's roughly the area of the lamp itself ... to get decent growth the lamps would have to be stacked close together.
    Don't worry about shocks ... they help keep you awake.

    • @ghz24
      @ghz24 8 ปีที่แล้ว

      +oz93666 I think your figures are a little off, a 400 w MH will handle the area you stated and it's not anywhere as efficient at delivering usable light per watt as leds.

    • @oz93666
      @oz93666 8 ปีที่แล้ว

      It said that a 400W metal halide is equivalent to 150W led (that's 150W electrical input to led's) . Also , for flowering (weed) max 500W.led per sq meter ...veg growth 250W

    • @ghz24
      @ghz24 8 ปีที่แล้ว

      +oz93666 It said 400w MH =150 w LED ???
      Where ? I didn't hear him mention a metal halide in this video at all .
      First watts isn't the right unit to measure light in but to simplify and make rough comparisons it is passably adequate (with minor adjustments occasionally needed).
      Not even sure if your most recent reply was agreement or not.
      Are you disputing the 400 watt MH will handle a square meter of grow area?
      Where did you get your 500w LED max figures?
      (not that I'm disputing them just curious)
      Why go for max W/m when you really want optimum watts/meter?
      And twice now you've said virtually the same thing
      1 "thats the electrical power delivered to the led's"
      2 "that's 150W electrical input to led's"
      I cant help but point out that watts is actually power consumed by the device and depends on the devices needs.
      Inputs would be voltage and amperage and in most home circuits can supply up to about 1500 watts (this is why all small plug in the wall space heaters max out at 1500 watts) but you can still plug in your cell phone and draw only 3 or4 watts.
      Not trying to be picky just specific.
      That watt rating is the amount of electric energy converted to some other energy like light or heat.

  • @kuhrd
    @kuhrd 8 ปีที่แล้ว

    At least it appears that the direct connection is only from the screw part of the base to the ground of the lamp since the screw side of a lamp socket is neutral and thus tied to ground in the US. With the bayonet style base and 230-240VAC I would be a bit more concerned. It does seem dubious that they didn't go to the extra length of completely isolating the lamp.
