mercury vapour

[nuckles]

just want to ask if anybody know how much heat mercury vapour lights give out.
I want to use one instead of fluro tube but i dont want much heat.
My tank is 25c without heat.
I tried a basking light 100w at one end and temp came to 50c under the light.
thanks

A 100W MVB will put out as much heat as any other 100W basking globe.

As i mentioned in a post last night, the temp in your enclosure will rely heavily on what it is made out of - An all glas enclosure will let the heat dissipate out of it at a faster rate, and will maintain a cooler temperature. An enclosure made out something more insulating like wood or thick plastic (like the URS vivs) will hold a much higher temperature, as the heat cannot escape as fast...

You can also take into account other factors such as vent size and location.

maybe I will keep looking at fluro tube and small basking light.
what max temp should I get under the basking light?

Depends on what animal your housing?

sorry bearded dragons.

If you are heating your beardies (as opposed to cooling them through winter), I would aim for a basking site of around 35ºC - 40ºC.
