Help - light melted!

Dimming isn't good. That bulb is supposed to be their "sun" when they are indoors. It shouldn't dim or turn off. The "sun" should come up and stay up for 12 hours. Again, control the basking temperature directly under the bulb by adjusting the height, the wattage of the bulb being used, or with a rheostat that can be set to the correct temperature. Your dimming thermostat should control a RHP or a CHE that doesn't give off any light and is used to maintain the ambient temperature of the enclosure where you want it.

Is that the cause of the bulb burning out prematurely? I don't know but it seems like it could be a contributing factor to me.

I have a spare on/off channel I can use. What do you think about 8in dome vs no dome?

An 8 inch dome should not overheat any bulb under 150 watts. In theory it should be able to handle a 250 watt if it's rated for that. Wider domes do a better job of spreading out the heat, and that is good. The domes I get from Home Depot are 11.5 inches, and they are relatively cheap compared to pet store brands. Don't you guys have a version of Home Depot over there?

We kind of do yes, but they still don’t stock them that big, least not from what I’ve seen

I worry is the second bulb to die in 6 months? The other one didn't separate just stop working, but still. Two new bulbs from different suppliers failing in a couple of months.

Whereabouts in the UK are you?

Hi and welcome.
I am on the UK a lot further south than you!
I use Swell Reptile for my supplies electronic and substrate so check there.

My set up has no dimming . I have a thermostat for the heat bulb 150w and both heat and UVB on timers.

Will send pics of what I have. I only have a dome in his holiday set up.

I'm in Essex. Do you have an exotics shop near you? My vet recommended 28 degrees Celsius by day and and 20 degrees Celsius by night. These lights don't like being turned on and off so I have a dimming thermostat fitted by my local exotics shop.

I would like to note: that the aforementioned Light bulb did not "Melt" per se. The typical ceramic adhesive that attaches the glass bulb to the brass medium base just came loose, it happens, but not frequently. It is made out of a ceramic adhesive, as to be able to take the high heat without . . . melting.
