Hi, @agmoore. Can you tell me where you missed the post, I might come in. Sorry about that though.

Regarding your question about halogen bulbs. Halogen lamp or bulb is a type of lamp that emits light when heated. It contains a bulb that's filled with a noble gas mixed with halogen (most especially iodine or bromine) under very high pressure. It emits UV because it requires a very high temperature to function. Halogen lamp works at a very high temperature, so it produce more UV light, just like the sun. I hope you know that the sun too emits UV light and it's even more intense now due to the depletion of the ozone layer that's meant to shield the excess UV light from the sun, as a result of our incessant burning of fuels and release of harmful chemicals into the atmosphere.

So, basically, halogen lamp emits UV and can cause skin cancer and some other harmful effect because it requires a whole lot of heat to function. But the harmful effects can be reduced through the use of special casing to cover the lamp.

Thank you for coming.
