Hi there!
That looks about right. My ReptiSun puts out about the same light. I don't think there's anything wrong with it at all.
Keep in mind it's not meant for bright white light, it's meant for
UVB light.
Your beardies need to be within 6-8 inches of that so if you moved it to the left side of your viv, along with that bright white basking bulb you already have, it looks like your beardies could get right up next to it and they'd get the benefit of the basking light and the
UVB light all at once, which is very helpful. :mrgreen:
Going by your picture, it looks too high up for them on the right side where you have it now, plus there's no bright light for them there.
If you want a bulb that will provide basking light, heat, and UVB all in one, you're looking for a Mercury Vapor Bulb such and the MegaRay or T-Rex.
Hope that helps
