Lighting China led to 1212

[Bungholio]

Hello there...

This is my first post here, So Bear with me

I have an old china led lampe, it have 6x 55-75v 600ma drivers, there is no watt info on them.

If i understand it correctly i should be able to put 2x clu048 1212 3500k cobs in each og these. And IT should run each led at roughly 20w or 2x6x20=240watt is that correctly?

I want to fit them on 3 square fixtures with 4 cobs on each for a 4x2x5.5 Space. 1fixture (80)w Per plant.


Does my idea make sense and is my driver/cob/watt calculation fight?

I believe that it depends if the driver is a constant voltage or constant current driver...if its constant voltage then i believe you cant use them with 1212's as they are a 35/36v COB and it would blow it unless im mistaken...

If they are constant current you could put 2 1212's on each driver...so you could have 6 Drivers Powering 12 COB's...so 2 on each...but without any info onthe driver its hard to say what it could be!

Well i dunno drivers Just say:
100-240v
55-75v
600ma

As these are 50 volt drivers, you should run the Citi 1812 or 1818 chips instead, they will work with these drivers.

 

[pop22]

actual output will likely be closer to 500ma per driver so your looking at 25 watts per cob. Will make for an excellent light thats very efficient as the cobs will be running at about 52-54 % efficiency.

Hmmm 50v ??? Well cool i Guess. So 6x 18xx Citizen... Back to check the specs at those

 

[Bungholio]

pop22 do you have datasheets for the 1818 too?? or is these sheets collected somewhere?

Also, I've no newer charts but the new gen chips that came out a couple months ago are a couple percent brighter and more efficient so these charts are off a bit to the low side.

For 6x 55-75v 600ma drivers youll want 12 1212 cobs, 2 wired in series / driver drawing about 70v / pair.
