Dense matrix array. I think that's a kessil term. They also produce dma's... it's an esoteric term to be honest. Call it what ya think it's called - a bunch of leds in one package. Sorry for the confusion!

I discuss them with the now banned Nemesis in depth here:

Well after weeks of negotiating with different led companies I have finally ordered a couple. Not anything super fancy just some ive seen all over ebsy and being used on other grow forums. The final price was one I could really work with so I pulled the trigger. They are still building one of the to my request and the other is going tto be their suggested spectrum. They have a " dimmable" feature and that just a switch for red and blue. I've just had alot of problems with seedling under my current led's that I'm curious to see how the do starting under just the blue spectrum. I'll post up some pics when they arrive. Here is a link to them on eBay.

that green one is very interesting romeo. I'll be waiting for your assessment:thumbs:

The green one is going it my new tent along with the 135w blackstar. The yellow one is going in my small tent. Should I just journal the whole grow in here starting with the blackstar? The other led's should be here in like 3 weeks. I could just add them when they come in and have a perpetual led grow.

Bought two 9W bulbs with E27 bases for cheap--each has 3 3W 'bulbs': 450nm, 630nm and 660nm (two cores). They have pretty solid looking aluminum heatsinks. Thoughts?
