[WTS, Limited Quantity] 40/80w 2828 COBs R9080

I have ordered a sample of 2828 COBs for CRI testing and I ordered more than I actually needed. So I will let some of them find a new home, if you are interested.

 

Stats:

 

Voltage: 34-38v

Amperage: 1200-2400mA

Efficiency: ~100lm/w @40w (1.2A), ~80lm/w @80w (2.4A).

CRI: R9080, slightly above B.B.L.

Output at 40w: ~4000lm

Output at 80w: ~7200lm

 

I will call these: 2828-35k-40-01 / 2828-50k-40-01 for 3500k and 5000k, respectively.

 

I have up to 20 for each CCT available, this is a limited run and I do not have plan for more of these (at least for now). Ask me about the availability first.

 

Pricing is $8.5/ea, fees included.

 

Shipping -- same as http://budgetlightforum.com/node/69056

Out of curiosity, what sort of driver would you need for one of these things?

You just need constant current (e.g. MEANWELL) drivers that can handle up to 36-40v (e.g. 27-40v constant current driver) with appropriate ampere rating to drive these.

Similar deal with the 100w floodlight COB and its drivers.
