48" ATI Sunpower

BiGGiePauls33 · Aug 29, 2020

So I picked up a 48: ATI Sunpower 8 bulb light for use over a Cadlights 100. What voltage setting should this be run on? Curious to see what others use, as there is a bunch of different answers I've found online.

I do not have that fixture, so I can only give you some helpful info. I looked into the light and it seems that, and correct me if I am wrong, but you are referring to the voltage for the fans to control the rpm. If this is the case them you will have to play with it a little as it is T5 temperature specific. You want to keep the bulbs around 35 degrees C.

Correct, voltage for the fans, but thanks for the information about the 35 degrees Celsius. Appreciate it @Billldg

Based on this video I decided to run mine at 4.5V.
