Capacitor Lot

Capacitor Lot

Does anyone know a way of keeping a HID capacitor cool for outdoor lighting?

I keep losing capacitors to the heat… I am using 105 degree Celsius rated caps but now I am looking for some strategies for keeping them cool another way. The caps and ballast are being used for outdoor parking lot lighting in hot areas.

Those enclosures are supposed to be designed with temperature
control as a factor.
Just some W.A.G.s.:
Is this a ‘refit from M.V’. situation?
(A step down in Wattage might be indicated.)
Are there any blocked cooling passages/vents?
Is airflow around the ballast compartment restricted?
Are the fixtures hard against the inside of a precast ‘pan’?
(Sometimes even a short stand-off nipple can give you some
more space for convective flow.)
