Lighting Citizen COB spreadsheet

[KonopCh]

Here I found nice calculator spreadsheet for Citizen COBs. Simply choose CCT and type forward current.

1825 is in my opinion THE BEST COB at the moment!! There is also 3618 but less efficient (but driven at 1.4A gives you 25000 lumens!). :drool:

Unfortunately I can't open it on my phone. Anyone feel like writing them out for us iphoners? From my chart the 1825 is definitely a bad ass light. The 1212 and 1812 are very easy to find drivers for.

Thanks for posting this konopCh I'm sure it will get plenty of use.

Anyone have efficiency data for Citizen COBs? Or know how to calculate them?

Anyone have CXM-32 datasheet? Efficiency, lumens etc.?

Check with cobkits.com he sells light engines based on them. My understanding it performs about like a citi 1812

My MOD420 is running 1825s and I love it! I just flipped it to 12/12 can't wait to see what flowering looks like it! I'm flowering Momma duck and some Blue Dragon photo periods.

What's the price like? I'm not sure I'd want to try anything new with the 350 cobs I have in stock and their proven performance so far. Under 165 watts my one photo plant looks like it's got a pound on it.

Cheaper than Cree. Like Citizen, but little better efficiency.

I think the chip is about $13.00
