Hi everyone, im new to the grow setup. For the past weeks i have been gathering information on indoor growing and lights and finally selected the CXM 32 series 100W COB from Luminus. Im growing one plant for now so only going for 1 light due to budget constraint. I am thinking to go with the Gen 1 CXM32 because it has more luminous flux than Gen 3. Im confused for which one to go ahead with. Which one will be best?

1. Luminus CXM-32-35-80-54-AC00-F2-3 (Gen 3) (cant find this model in the data sheet)
Check specs
2. Luminus CXM-32-35-80-54-AC00-F2-3 (Gen1)
Check specs

Also the color of the COB mentioned is Neutral white, i cant find warm white on the site. Will it work fine?


Also im having a hard time choosing a driver to run this COB. The forward voltage of this COB is 51-54V, i have chosen some meanwell drivers, but i not sure if it will work. Can you please help me choose an appropriate driver (with dimming ) to run this COB.

Driver i chose: ( Im noob)

1. Mean Well HLG-60H-42B
Check specs

Thank you,
Peace

The gen 3 cob you linked is lower voltage with lower current on the data which is one reason its putting out less total lumens because its been run softer and using less power than the gen 1 cob you linked.

Gen 3 13800lm , 51v, 112.2w
Gen1 16880lm , 54v, 146w

Theres also the difference in cri rating, the gen 3 you linked is 90 cri and the gen 1 is 80cri

90cri tends to look worse on paper lm/w wise. But I prefer high cri.

As for drivers, you linked 60w driver with a voltage of 42v, you would want a voltage of 54
so a hlg60-54 with an a or ab on the end will work, the a/ab means the voltage is adjustable.

However having said all that I don't think COBs are the way to go as far as lm/w vs cost goes.
The price of a pin heatsink can make it much more expensive depending on where in the world you live.

There are other ways to produce a more efficient LED set up at less money
Like a 4 pack of hlg132s or a few bridgelux eb strips or samsungs f series strips.
Maybe look at ledgardeners site and get some ideas.


Edit , the gen 1 is very low lumen per watt.

Thanks a lot for your help bro, your. explanation made it much easier for me to understand. I will have a look at LEDgardener and read more.
