| I have been using a ceramic bulb with a regular on-off thermostat for 3 years now, and am still on the original bulb. This was my first enclosure so I just went along with what the shop told me. I should change the thermostat to a dimming one, but haven't got around to it yet.
In another enclosure with an on/off thermostat I tried a Black Light Ceramic bulb and it only lasted 6 months. |
