Was looking around Home Depot aka the Candy Store, and found a few interesting lights.

Are these CREE LED bulbs the same brand as the CREE LED's everyone talks about? They come in 2700k, 5000k, and 6500k. I bought a 2700k to see how it works. What do you guys think? Could a bunch of them be useful for flowering?

There are also these MH and HPS lights. Would these be effective for small scale?

The LED bulbs work very well. There are very cheap lamp holders for under $2 and you'd need about 4 per square foot, so for a 3'x3' area you'd need 36, if you want high intensity. A fair amount of wiring is involved, all parallel wired. You could use half that many and it would probably still work well enough. Total cost for 36 bulbs and sockets would probably be around $300 and it would be about 600 watts so 50 cents a watt.

I'm currently ordering 2x 70w Phillips Master colour cdm bulbs to run off this square wave ballast. Still need to look into 24hr operation but pretty sure its fine from all ive read so far. Does anyone have any experience with these?

I can attest to the HID lamps from Home Depot working. They don't produce the spectrum horticultural bulbs do but they will get you started.

Thanks for the reply! Good news!

Awesome, we shall see how everything turns out. I'm in the process of building a bigger cabinet, and that one will get some good lighting.

Which lamp holders are you referring to? Like a household socket? I have them those sockets with the clamp attached for now.

Here's a pic 17 days into flower!

One of the first two on this page. They're actually cheaper than a bare socket, which I would have bought if they were that cheap. Another idea I thought of was to use these screw in things with a socket and two outlets on it. The idea is for those outlets to make it easy to daisy chain them, using solid copper wires and just stickiing the bare ends into the prong holes. I would probably mount them by drilling holes in a plywood sheet the right size to be able to screw them in there. I would put tape over the end contacts to avoid any possibility of a short or shock. They cost over twice what the other sockets I linked cost though, so it's a fairly high price for easier daisy chaining. What makes it hard with the first sockets is that to wire a string of them together like that requires breaking off part of the side of the plastic base so the wires can fit under it. I suppose you could just run the wires under and leave a space between the base and the mounting board the thickness of the wire, since nobody will be looking at them anyway.

Also, when I commented before I didn't mention that I haven't used the Cree brand of bulbs before, just the Osram/Sylvania ones. The Cree ones have the same lumen output per watt, 100 with the diffuser on, probably about 120 with it cut off. The Crees are higher wattage though, 16.5 vs 14 with the Osram 100w replacements. So if they were a similar price, the Crees would be the better deal, as long as they don't burn out quicker or anything. I've only had one Osram bulb burn out yet, and I'm running about 20 altogether of various wattages and have been for probably a year or so.

Actually I just did a search and turns out the Crees cost a fucking fortune. I would stick with the non dimmable Osrams.
