WTB: LED stuff... 3w diodes, heatsinks, dimmable drivers

[AndrewK]

May be a long shot but I am looking to build a new DIY light fixture for an Aquarium I am setting up.

Things I need:

3w LEDs... any brand and any color (mostly looking for 6500k, 420nm, 450nm, and one or two 660nm)

700mA PWM dimmable drivers (something like the Phillips advance LED series)

12-36inch long aluminum heatsink (prefer something from a kit like the Makers heatsink from LEDGROUPBUY)



Let me know what you have and what you want for it (pm or post here). Figured some people might have leftovers laying around.

Thanks,
Andrew

i got old LEDs in my basement.

I have a few CREE LEDs around (unsure what wattage, they're from Aurora C6s), and some LM317-based constant current linear regulator-style drivers (not PWM).

I built a light for my shed the other year using these, similar to what you have in mind.
