I have posted about my 2 year old Hubble 250w wall mount lights from Kleenrite before and I'm still in the same boat. Kleenrite and Hubble are Worthless! I purchased 16 of the lights, my line power to the lights is 208 single phase(208 three phase at the panel) My meter checks in at 214volts at the tranformer, I have gone threw approximately 30 capacitors and a good amount of bulbs. Yes they are wired correctly and yes the capacitors are the correct size. I'm guessing that heat plays a role in this because its worse in the warmer weather. Now that the weather has warmed up this week I have three lights down again tonight, I have emailed Hubble one time and have asked Kleerite to ask there suppler about my situation two times in the past two years and they never get back to me so I guess this is just another learning lesson for me!
