Now I’ve had no problems with mike but of course I want to get some spares lined up for any emergency. I currently use the 100w zoomed bulb I have a montaine species but the room he is kept in is very cold to where even with that powerful a bulb the warmest is 82 F on his basking branch. But let’s say I wanted to switch it up or just have spares would a flood light or spot light be better?
Definitely a flood. I'd never use a spot; the heat is too concentrated and boom—you go from ambient 70 to 80+ in one step.
The types of bulb—in order of preference—are (IMO):
- No LEDs
- Incandescent household bulb
- Incandescent flood light (NOT spot)
- Halogen flood light (NOT spot)
- Ceramic Heat Emitter (CHE, which can be used in conjunction with an LED)
And if I go with a halogen how much stronger are those compared to incandescent ones?
Unless you're replacing the current bulb with the exact same thing, it's going to be trial & error; you'll have to re-balance everything—distance from basking site, angle, type & wattage of bulb—to get things right again.
My current one is one of those rounded ones it doesn’t even have that reflector shape would a reflector shape be better?
For something like a household incandescent that radiates in all directions, yes.
Something like this:
For something like a flood that has a more aimed beam, no; a reflector is usually integral.
To review, basking bulbs should be mounted
at an angle to the basking site. This will provide an
ellipse rather than a circle, which inherently produces a
gradient of temperatures rather than a constant. The gradient allows for the [reptile] to seek the temperature it desires,
and helps make up for small fluctuations in some of the other variables.
