Found them for 400 for a 300 watter on EBay.

That is wayy cheaper than at advancedledlights.com.
Anyone have experience with these and/or this reseller?
For my first grow (2x4) I kinda had decided to go with a Lumigrow Pro 325 or CLW Solar Storm 400, but i sure would not mind doubling the output and saving 100$ with the Adv. Diamond 600. But then again will extra wattage output give a higher yield compared to a higher quality but lower wattage unit.
Researching LED lights is frustrating, i seem to find two more manufacturers and two more variables with each hour passed.
Week four and still not flowering. Never have I grown sensi star and it did not show some signs of flower within two weeks. No pistols at all, like its still in veg mode cycle. You can take it however you want, but I will never buy another one of these lights (from this ebay dealer).
I bought 3 300 watt equivalent 2700k CFLS at lowes today and threw them in the grow closet. They're huge and cheap.

I found this at ebay: Blackstar 240w
Looks good and not to pricy. Anyone with experience with this lamp? I am most concerned about heat.. Im thinking about using it on top of my 250w CFL vert grow and my temps are perfect atm.
A question for the gurus, what needs to be done if anything when swapping out red beads for whites? The reds run at a lower forward voltage than the whites, will the resistor need to be changed? Or is it just a straight swap?
What this tells me is that it is a straight swap. I should have parts today or tomorrow, soon the experiment begins.The increased voltage drop across the string means that, to achieve the same current, the supply will operate at a slightly higher voltage. That should be no problem for the driver you linked. It will increase voltage to maintain current.
Welcome to the forum. As to your question there are several threads you might like to read, hopefully they help.

I'm almost certain that I have read that the Blackstar LED's are very similar to the China lights in that they utilize similar components. The light is listed as 240w, it is assumed that it is driven at 2/3 power so actual output watts are around 160, heat gains should be minimal. As for pricing, if indeed the Blackstar is similar to the China light then pricing is an issue, as you'll get a much bigger bang for your buck with the China light.

In this thread we are attempting to evaluate the usefulness of the China light, you might want to wait and see what happens here before you shell out for a Blackstar.
