Hi dear friends,

I'm sorry in advance for my bad english. This is not my native language.

I have been following the posts in the forum in the few last months.

A few months ago I ordered from timber two kits of 300W and one of 200W.
(Dan amazing guy! With excellent service! Highly recommend)
He advised me to watch Growmau5 to learn more about LEDs.

I'm no expert, but I see that the community here and just want to help and share knowledge.
(On this occasion I will mention specifically the Growmau5, although we never talked personally, his videos and comments were a great help for me)

Next session, I ordered another 60COBs of CXB3590 with 12 drivers of Meanwell HLG-240H-C1400B.
In order to reduce the costs I ordered the parts from Kingbrite through alibaba.

I am looking for a suitable potentiometers.
I read the post "MeanWell LED Drivers: 3 in 1 Dimming Function" of Stardustsailor.
Because of the language barrier, I could not calculate what exactly is i need.

In addition, i want to run four drivers 240h an area of 1.2 square meters,
and i want to control through a single pot for four drivers. Is it possible?
If so, what pot I need?

Further to what I wrote above, i was using a 20 COBS an area of 1.2 square meters - is it important to use lenses?
I ordered reflectors for all the COBS, but there was no lenses in stock.

I'm sure I can learn a lot of of the forum members and I would love to expand my knowledge from each one.

Thank you dear friends :-)

For 4 drivers you would use a 25k pot. If you run 1 driver it would be a 100k pot and for 100 drivers it would be 1k pot. You should be fine without the lenses. I only use lenses on my LED work lights to protect from dirt.
