There is a lot of variation with halogens so I just can't say for sure. I can tell you that most 150 watt halogens will get A LOT hotter than a standard 100 watt incandescant, at least based on bulbs available in the US.



Halogens also tend to concentrate the heat more directly.



I'm afraid you're just going to have to pick one and see how it works.



I have to say I've never been a big fan of the bulbs than focus the heat more, whether they be halogens or reptile specific, especially for heat loving species like Uromastyx. There are sitations where they work well but every situation is different.



Again, you're going to have to try some things and see what works.
