    I just got in a shipment of my custom-made LED lamps, and with today being my birthday, I thought I'd have a special on them.

    LED_1-400x400.jpg

    They consist of 64 chips, in a combination of bright white, warm white, and red diodes to improve flowering while keeping good color rendition. There is a clear plastic "splash guard" over the chips, so they are great for terrariums. They are rated at 13 W, can be used with 85v to 265v circuits, and screw into a standard incandescent socket, while having some rotation in the base so you can line them up. Output at one foot distance has been measured at a PPFD of about 50-55 ┬Ámol/sq, m/sec, which is about 90-95% of a 2', 24W T5 bulb.

    I have one about 12" over some phals and African violets in a dark bathroom, and they all grow and flower nicely. At that height, they're good for about an area 2' square or so.

    The first of these I got in sold out at $29, and I have been able to lower the price to $24 each (with discounts for multiple units), and the special now has them at $20 each.

    Do these just screw into a standard fixture?

    Yes Marni. They will fit a standard US socket. I find that the work better with a reflector even though the diodes face the same direction. I have no complaints about them after a year plus of use.

    Do they put out any heat. I am always looking for lighting for the increasing number of flask shelves and heat is a problem in some cases. I guess it is time to try.

    I have not measured the heat output exactly. What I can say is this:
    I have a tank measuring 36" long, 18" deep and 18" tall with Paph seedlings in it. The tank has 2 light hoods over it that rest on top of poly carbonate sheeting. The total lights over the tanks consist of 2 of these LEDs and 2 CFL bulbs. From this I may only have a 2-4F increase in temps. I consider it minimal. Hope that helps a bit.

    I turned mine on all day today. Excited for my windowsill odds and ends to grow better.

    I have 2 of these over a 2x4 shelf with flasks. The light is surprisingly nice and the coverage is good. I am especially excited to see how they do since I have a problem with the T5 of heating the shelf above and that means I have to choose carefully what goes on that center strip of shelf above the light and a problem for cool growers.

    What's a good reflector for this bulb?

    You don't really need a traditional reflector, as 100% of the light is emitted from the face directed at the plants, but if you want to narrow the beam, I have used aluminum "step flashing" from the local Lowes or Home Depot (about $0.85) to make them. Be sure to create some holes to allow free air flow around the heat sink/case.

    I bought some of these when Ray first put this up. I've just bought more and am very happy with them. I've been using 2 bulbs per shelf but may end up using 3 per 2 x 4 ft shelf to get really even coverage. That is still less watts than a single 4ft T5 and will be better coverage. I tried a couple of cheap bulbs from China for a comparison and will stick with Ray's. I don't know how much the plants care, but I like the quality of the light with the red diodes and since I have to work around them that is important to me. Thanks, Ray!

    Ray, what do you tend to use to hold the bulb? I just one of these to try out and am very excited, but it's proving harder than expected to find a lamp that will hold the bulb properly over my plants.

    I would be interested in what Ray has to say, but depending on what your set up is, I found a very inexpensive solution from inexpensive parts from the hardware store (under $10). I am installing them underneath a wooden shelf. I started off using a dual flood light fixture that I had already. I am lighting a 2 x 4 ft shelf so was using 2 bulbs. The fixture shown had the bulbs a bit to close together for even lighting so I bought some of the individual parts and am using 2 of the plates and 2 of the sockets but they are separate and I wire them up to a cord. I have the 2 lights running on the 4ft center line.

    I have used a number of different methods - goose-neck or articulated desk lamps with the shade removed (in this case, the lamp was spray-painted black to match the base
    , LED_Desk-Lamp.jpg

    I have also used clamp lamps, again with the shade removed

    I am using holders like the one in the upper right of this image is great for holding pairs of lamps in a seedling enclosure.

    I just got more of these back in stock, and have decided to keep the $20 price.

    Thanks Ray. If they died out more often I would buy more. I still have the first ones running strong. I guess that is a good thing for us and not so much for you. I have decided to not go through with anymore T5s as a result. I have to replace those damn things constantly.

    I am switching over to these for the flasking shelves. Since I started buying T5 fixtures about 3 years ago, a lot of them have gone bad. I have yet to burn out a tube and I now have a good supply of tubes with no fixtures. The company has stopped taking responsibility. I was using 57W bulbs, 4 ft long for a 2 x 4' shelf. I can get by with 2 of these for the same space which will cut my electricity costs substantially.
