is it possible/worthwile?
lead goes to 10w chip then to 2 parlell series of 3 watt chips starting with blue(highest voltage) to amber to red to the other lead.
parts are listed below, and its a 4.8" x 5" heat sink big enough? power supply proper?
also i know ebay is not ideal so links to some good leds is always helpful but keep in mind i got the cheapest best setup in mind here.
trying make 3 30w mini panels. (buying the extra chips for future leds) might switch up the 10k to 6500 or maybe even warm white(or get one for each panel) but im thinking more to use these lights to supplement an HPS and one to veg with then build 2 more for adding to a different hps

130$ for x3 driver x3 heat sink x3 fans x3 10w leds x10 blue 3w x10 660 3w x10 630 3w

It is 'possible' but since wave lengths differ, not sure mixing low watts will help. Some of the new fixtures are using multi-chips with reflectors

You can buy multi-chipset floods very inexpensively http://www.ebay.com/itm/10W-20W-30W-50W-Blue-554nm-Red-660nm-Hydroponic-Plant-Flood-LED-Grow-Lights-/251248529710?pt=LH_DefaultDomain_0&var=&hash=item3a7f94512e

I really dont see much point - you will have to position your panel with at least SOME of the diodes at sub-optimal distance.

yeah ive seen those charging a little too much tho. you can buy like x5 white at a time for 120$ which isnt too bad, might be able to get them 1$ per watt with some emails.

@snotboogie im not sure i agree, yes there will be som variance in intensity between the differnt diodes, the point is really to fit more watts in smaller space.

The amount of "watts" your plants are ACTUALLY getting is subject to the inverse square law - the further away your panel is, the less they get. On the other hand, have your big blue diodes too close and your plants will show all the abnormalities of excessive blue light.

will not work, mismatch between needed minimum driver voltage(28V) and the led voltage(21V).

minimun configuration for your driver..
