    LED grow light users

    Hello,

    I'd like to add more lighting to my indoor HL chamber as of right know I have a 4 tube T5HO fixture. It does its job but I'm interested in supplementing with some LED grow lights. What are you guys using and what brands and models do you recommend? I'd like to stick to the high quality stuff so I'm not have to repurchase later on so to shoddy manufacturing. the area I'm looking to light is 36" tall 48" wide and 36" deep.

    Looking forward to your replies,
    Jess

    I strongly recommend building your own system. Cree has some really nice solderless XMLs. With a custom set-up you could always add more/less lights to your heatsink or later buy a different heat sink as well. rapidled has some good products. Check them out.

    As raisetup01 said, if DIY is a possibility (very easy), you get the best bang for the money. COB based ones are even easier than smaller ones like XML2. Bridgelux Vero 18 and 29 4000K is something I would go (for the initial price and high efficiency). But Cree CXB3070 is great, too (a bit more pricey). 3-4 units of Vero 29 or CXB3070 driven at 50W each will cover the area well (each unit will be around $60-70). Here is a link to how-to which I wrote (it uses an older CXA3070, message #16):

    I recently found an affordable T8 LED, which can do >140 lumen/watt, by browsing DoE Lighting Facts database. This could be a game changer.

    If you want pre-build one, an independent test has shown high PAR efficiency of Build My Led units (I have no association with them, and I'm not sure if I'm allowed to put a link here). There are lots of bogus marketing with the so-called LED grow light, so be careful.

    BUILD YOUR OWN. Get high quality LED lights and a driver and heatsinks. I don't trust those red/blue led "grow lights" sold on ebay and amazon anymore. I've bought a couple of those then built my own with components from RapidLED with EXCELLENT results.

    Let's pretend, just for a second, I am a fairly handy person who can follow a walkthrough, but have never built an LED system before, what exactly should I be looking for in the LEDs/components. Also, is there a decent walkthrough anywhere for building it from steps A-Z?

    Some of the solderless kits are very nice. I ordered one from them about a year ago and have had great results. There are also some great threads on here about light quality and wavelengths. It shouldn't be too hard to figure out once you take a look. Also, RapidLED allows you to customize your light selection, so in some of the kits if you specify in the order that you want certain wavelength lights, they can substitute them out. I recommend them highly

    yep its super easy with the solderless LEDs. You dont even have to drill holes in the heat sink to attach them. you can use glue that they sell but it will be permanent.

    i got the this kit: http://www.rapidled.com/12-led-plug-...-retrofit-kit/

    I ordered 12 xml2 leds and this heat sink- http://www.rapidled.com/6-x-12-premi...and-enclosure/

    Im sure there's a "walk-through" somewhere on the internet but it's pretty self explanatory when you just need to buy a kit

    i made a topic about my light: http://www.terraforums.com/forums/sh...grow-light-kit

    I say it's tedious putting the screws in that particular fixture but i have pretty large hands and those screws are tiny. I got about three done before i asked my girlfriend to take over. she had no problem really..

    if i were to do it again with that same kit and fixture i wouldnt have gotten the dimmable version. Since it has a fan, i can run it on high and it never gets hot. I don't use the dimmer but i guess its a neat feature anyways...

    make sure to read this too: http://www.terraforums.com/forums/sh...uld-love-input

    It's what gave me the confidence and convinced me to build my own
