    I'm putting together a little grow cabinet and wanted to know if there's any recommendations on any LED bulbs i could use?? inexpensive ones if possible. I I would go with CFLs but I've heard LEDs are way better. Any info is appreciated. Thanks.

    V22 cob $11 , driver maybe $50, PC heatsink and fan maybe $10 and an old wallwart from a drawer to drive the fan on the heatsink., will light a foot and a half diameter circle.

    Do not buy a mars light or any of those inefficient Eepistar assemblies with their light robbing plastic lens caps. They belong back in the last decade.

    If you REALLY must go that route, Home Depot sells 9W 800 lumen Lumitech led bulbs for like $1 on sale.
    Get a lightbulb base-to-outlet plug adapter for each bulb you plan to use and plug them into a power strip.
    Remove the diffusers from the bulb to achieve more lumens.
    Cheap and easy, but you get what you pay for when it comes to lighting so I wouldn't expect much more than mediocre veg lights.

    You're probably gonna want more than led light bulbs in my opinion..
    lets say you want to get 150W of light in there. You can put a 150W hps light in there which puts out roughly 16,000 lumens.
    To get the same lumens in those led light bulbs as that hps light, you would need about 20 of them.
    At 9W 800 lumens per bulb x 20 led bulbs = 180W for 16,000 lumens.
    The hps seems a better choice to me since it will be the same lumens for 30W less power used to get it (and likely less money to put together). Plus you can get a 150W hps light from Home Depot for like $65 bulb included.
    Im just assuming your keeping the budget at an absolute minimum. If you have a few more $$ we can talk about better options. How are you cooling the cab? Dont be fooled by the hype you hear about led's. They put off heat too and your cab will need exhaust for air exchange and cooling. Then theres the smell and how to get rid of it and so on.......
    @whitebb2727 has an oak cab build that would likely be beneficial for you to check out. Hes got it laid out rather well.

    Wal-Mart has their 100 watt replacement bulbs that draw about 14 watts and 1100 lumens. You can get 4 packs for 10-20 bucks depending on the year rating. They have 6500k and 2700k.

    I would suggest getting a 200 watt diy citizen or Vero cob setup.

    I have used the 14 watt ones. Remove the globes.

    I started with t5 and it grows some great pot. Here is a link to my cab.

    Home depot also has cree bulbs, 4 packs about $1 each. Cut them diffusers and grow! Be warned these things can burn your plants!!! Second thought, you may want to leave the diffusers on, maybe run a couple extra bulbs.

    How sure are you? And also I'm mainly worried about flowering I'm only vegging for a couple of weeks considering my box is small. Its a 3 ft tall x 2 ft wide x 1ft deep just measured it

    I think im going to piggyback this idea to make some supplimental light bars for the edges of my flower room... i dont need a horsepower light thats already going im looking for a boost as it fades off, i think those incadencent replacement LEDS b great for what im looking for

    Been done many times before me! Excellent thread on ic mag showing the differences at varying heights between cfls, and led bulbs both with and without the diffuser. I cant imagine any cfl user not switching to these after reading that thread. Granted it is a lux meter so not the full story but the difference in output/watts leaves alot of wiggle room. Removing the diffusers is huge. The price for that though is they will burn your plants at distances of just 12”. Some strains seem to tolerate it better than others. Its a low and slow thing. By the time you notice, youve done some damage.

    $60. Its a diy build. Cree 4 packs of bulbs, $5. The boxes are outdoor flood light socket and junction boxes mounted to 1/4” polycarbonate with 1” aluminum c channel rails for rigidity and mounting.
