Citizen leds?? Citiled anyone used??

[oill]

Hi guys,

There is a new budmaster light, and it uses citiled LED's.

Anyone used?

From this page... Which ones would you used on a 1m2 space??

They go up to 500 + watts.

That's one hell of a selection of cobs, my god

Hey guys. Adding you 2 pros. You seen these??

Looking at the datasheets the Citiled 3000K has relatively more blue than the CXB3070 at 3000K
Red looks to peak at the same nm.

105 dollar for a 243 watt cob (when driven at 2340mA) that gives 130 lm/w at 85 degrees seems like a fair price.

I have a couple of the CLU550. It is only slightly larger than a Vero 29 but twice the power.
I am ordering the holders today. They can only be driven at 2100mA unless someone can find a 240-2400 driver.

Sorry... To be clear on the take away from your comments... Does that make the vero better?

Twice the power you mean wattage? Out output?

Thanks

He means wattage yes.

Output is probably +-twice as well

Both. The 4000K is over 140 lumen per watt. It is just another way to build lights. These light need to be around 30" above the canopy.

Does that mean this is more like moving towards an hps?

How many would you use for a 1m2?

 

[coolj]

I have some, building lights now!

Sweet. What driver and how many over what space??

 

[nevergoodenuf]

Whit, with CDIWeb.com, Just finished has been very helpful with my Citizen build. He toured the Tokyo plant yesterday and is sending me 5 sample holders for free. Should be able to get some output numbers by the weekend.

Interesting never knew that cobs went over 100 watt, what kind of driver will you need for them, as I have only seen 100 watt ones too.

 

[nevergoodenuf]

2 HLG120H-1050 or one HLG240H-2100 for one CLU550. The run at 108 volts.

I'm currently using the Budmaster COB's and also testing out their GOD series panels. The COB's I put in a flowering garden that was already on day 30, but they finished out the plants on day 70 very nicely. Not a true test because the plants were already flowered so I am running some new plants under them and currently in early veg.Each one of these panels is drawing 200w +/- 5W. The plants were all tangies from seed, all different pheno's.

looking at the datasheet for 3500K@80cri, 25C
based on CDIs price of $103/COB

400mA
~98V
~39W
~6950 lumens
178 lumen/w (~55% efficient)
$4.80 /PAR W
compare CXB3590CD @55% efficient = $1.53

1000mA
~101V
~101W
~14940 lumens
148 lumen/w (~46% efficient)
$2.22/PAR W
compare CXB3590CD @46% efficient = $1.12

2000mA
~106V
~212W
~29532 lumens
139 lumen/w (~43% efficient)
$1.13/PAR W
compare CXB3590CD @43% efficient = $0.94

no thanks. efficiency cant touch the cree on a value basis. even if you got a hookup and got them for half of CDIs list price CREE beats the pants off it at anything over 50% efficiency

that is impressive hi temp performance. youd need 3-1/2 3590s to match it at that temp

130 lm/watt is still only 40% tho, kind of well below where most COBbers are running these days

CXB3590 scales way better at lower currents

citizen@25% of reference current(590 mA) = ~25% of lumens
3590@25% of reference current = ~31% of lumens

I really want to try out the cluo46 1818 3500k, i think 70cri, but maybe thats just the 4000k and it would be the 80 cri for the 3500k. Anyone know how those stack up efficiency wise at 1050mA?

 

[nevergoodenuf]

Well, it looks like I will have a discount code for CDIWeb soon. Whit liked the idea and said he will get on it when he gets back from Tokyo. As for the efficiency of the Citizen, at this point any light that is over 40% efficient is a win in my book. I will soon have a 500 watt fixture done, just waiting on the new holders. I have a few different tests starting at different wattages.
