JBJ Macro-Glo Fuge light?

does anyone have any experience with these? I purchased the 15 watt version (comes in 25 watt as well), and was wondering if anyone knows whether or not I can use a 25 watt bulb in the same fixture. After reading this, it leads me to believe I can.

 

If the bulbs were interchangeable, they wouldn't sell two different models.

 

Why not? If they can make an extra dollar by just having a different bulb in the thing? Seems to me that the bulb is 110 volt, and each bulb has it's own ballast. No?
Just thought I'd ask, as there are many members here who are very knowledgable. I'll call the manufacturer directly and ask them. I'll post my answer here in-case anyone else ever wants to know.

 

I just called JBJ and they stated that I can use the 25 watt bulb in the fixture.

 

So what's the difference in the two models if the bulbs are interchangeable?

 

Apparently, the 15 watt comes with a 15 watt bulb, and the 25 watt comes with a 25 watt bulb. Unless they are pulling my leg. I'll let you know how it goes, if I decide to change out the bulb.
Whats you interest in this? Do you have one of these lights?

 

Well, it was time to replace the light bulb. I purchased the 25 Watt version, and it works. It's a little tight fitting, but it does fit and it does work. What a difference in brightness.
