Mercury vapor bulbs?

Has anyone had any experience with these?

I got one for my turtles, and it lasted ~12 hours. I hung it vertically as per the instructions. I was largely unimpressed. It raised the surface of the basking spot only 3 degrees, and raised the ambient room temperature *2* degrees.

No you cannot use a dimmer with them, it will malfunction and possibly cause a fire.

I didn't use a dimmer. Used a zoomed in the recommended zoomed deep dome fixture. Looking into the warranty, until then I'm using two fixtures.

Re: Mercury vapor bulbs?

I had a mercury vapour lamp as well as a basking lamp for my bearded dragons. The MV lamp was really only used for UV and to keep a steady ambient temperature. It is actually (in my experience) a very good long life lamp but it does not work well with moisture. If there is a lot of moisture in your enclosure the lamp will die rather quickly.

Sound like that would be your problem. To much moisture. I would use ceramic heat emitter. Not cheap, but last a lot longer than any heat bulb. Plus moisture won't be an issue with these.

Re: Mercury vapor bulbs?

all i use for my RES are MV bulbs. when i switched from heat/UV bulbs i found it easier to keep up higher temps and my RES just brightened up with colour ive never seen before because of the high UV output.
