I tried this once. "Tried" being the word.
How do the hell do you remove the glass lens?
Gently???
I honestly tried a hammer & nail to shatter the lens...even a screwdriver to chisel a wedge...no luck at all without risking damaging the entire bulb.
well I just ordered a reptile grade mvb from ebay 30 odd dollars better then paying 70 at my local reptile shop couldn't find mvb anywhere else.
yeh they look great thanx they also got fluon which is sold out atmOne of the sponsors or more of this site will have them

Correct my naiveness but I always thought two different light spectrums would clash & possibly alter the uv qualities...?
No,I'm sorry if I've caused the confusion. You mentioned using a 100 watt spotlight from Bunnings which is a light that just happens to give off heat due to its intensity.
I was just simply wondering if its spectrum would clash/alter any other light source?
Would the B alter or disfuse the A?
I think I might juz be confusing myself...

I have also tried and failed to remove the len without breaking the reflector. There is a reptile branded diochronic bulb sold in pet shops without the lens but you pay more for them.
Sorry guys i should have explained how i did it,: i have a butane gas soldering iron that also works as a mini butane burner if the tip is screwed off, i used that and a disposable scalpel (available at most chemist shops or from a friendly herp vet) first i heated the area where the silastic type material holds the lens in place and then using a combination of the heat and scalpel i gently prized the lens off, it might be best noted that the lens wants to go back into it's original position when you first start out so get a few tooth pics and slip them between the lens and reflector (being carefull not to push tooth pics too far and possably damaging the filament) just take it slow and easy using the same patience you use with a juvinile snake and you will not crack the reflector, if a clumsy old man like me with fingers like fijian banana's can do it i am sure you all can do it as well, slow and steady breaks the seal, oh and please use protective gloves and eye protection .......................................Ron
Cheers Stevo & Silverbeast for understanding my confusion & then explaining the reasons why...
I was looking at the spectrum as colours. One source may be giving off red, the other blue, but once they intersected with each other you'd no longer see the true individual colours.
Interesting read on Dichroic Halogen Lamps... Good or bad? I'll let you decide... Check it out...

Interesting. I have wondered about the amount of UVB and the possability of dangerous UVC but never about bulbs exploding. These lamps sold for many years without the glass cover and never heard of big risks of exploding lamps. I have only seen them in the past few years all advertising the covers as UV blockers.Interesting read on Dichroic Halogen Lamps... Good or bad? I'll let you decide... Check it out...

While I hadn't found away to easily remove the glass and not knowing if it was even worth the effort I have not used them for UV. They still make great heat lamps for some small enclosures but you do need to have a heat guard over them. I also supply reptile UVA/B compacts for these set ups.
The article is also interesting about the mercury vapour lamps not specifically for reptiles with ordinary glass fronts blocking the UV. I have used alternative mercuray vapour bulbs sold cheaper than reptile branded ones. I have not seen any problems develop from these but I also use calcium with vitamin D suppliments.
The UV meter I have is a broad spectrum combined UVA and UVB and found its use limited in indicating a bulb is due to be replaced. Looks like the model they decribe in the article is the only one out there that can tell us the real UVB level.
