I was wondering if anyone could tell me if using the dimmer function on my 315 watt light would hurt a Philips 315w bulb? The first bulbs I got came with my hood so I did not have any reservations about using the dimmer function with it. After those bulbs wore out I upgraded to the Philips brand 315w CMH and I didn’t know if using the dimmer function on my lights from 315 Watts down to 245 Watts could cause wear and tear on my bulb. If anyone has any knowledge of this I would appreciate some advice. Thank you hope everyone has a good day.
