Lighting New citizen cob

[2Stoned2Care]

Hi everyone i just wanted to know what you guys think of the new citizen
CLU550-3626C1

if i am reading the specs right its a 295w per channel 2 channel chip thats a 595w chip.with the test amps at 2.34a giving typical lm 32500 thats about %50 efficiency and 295w but i would drive them at about 1.4a

now they are expensive £108 a piece but if they are as good as the specs say i would only need 2

I saw that too.
However, I would rather buy something smaller (and more) and spread them at the tent ceiling.

Well... if you have bigger tent then buy 4-5 of them. Hell yea, excited about new technology.

It's more like 1-2 per 4x4. Comparing efficiency and cost the 048's might be a better choice but still very interesting.

I just found this info
1000mA
~101V
~101W
~14940 lumens
148 lumen/w (~46% efficient)
$2.22/PAR W


2000mA
~106V
~212W
~29532 lumens
139 lumen/w (~43% efficient)
$1.13/PAR W

So it's best to drive them harder@1400ma you would be close to 150w per chip. Dayum

yeah thats what i was thinking 2 150w on seperate passive or active heatsinks because my space is only 50x100(1.6ftx3ft)

Money is not a problem i just want the best i can get for the tent i have,what do you think the best setup would be

The 058 1825's are the most efficient cobs I believe
183 lm/w @500ma
168 lm/w @1400ma

At lower amperage and wattages the 1212's are very comparable to the 1825's but once you get them up to 50w 1400ma they start dropping

gen 7 vero 29s are supposed to get 160@1800 (3500k)

And the iPhone 6 battery was supposed to be 46% bigger. Lol jk what's the price point?

 

[InexpensiveBeret]

digikey has them for 22$ (when buying x50, they're not in stock yet). they also list lm/w@1800 at 148, significantly lower than the data sheet.

i'm not comfortable guessing the price for small orders, but if it's under 35$ it seems like a pretty good deal.

 

[2Stoned2Care]

So many decent chips to choose from its making my head hurt lol

hey i figure it just means you can't go wrong
