Do Halogens Give Off More Heat?

Halogen lamp

Q: Since halogens give off more heat, do they present a fire hazard for lamp shades? Will the halogens make the shades deteriorate faster?

A: Halogens are twice as hot as standard incandescent lamps. If a table lamp is UL-rated for 75W, it is referring to a standard household bulb. You can’t replace it with a 75W halogen. So I do believe that there is a greater likelihood of shade material catching on fire if it is lamped with the comparable-wattage halogen, but more likely the halogen lamp will more quickly degrade the shade material because of the increased heat and ultraviolet light that it emits.

If you’re using halogen to get more light output, consider a compact fluorescent. Both MaxLite and Litetronics make a three-way fluorescent bulb, giving you three levels of illumination as you turn the switch. Or you can use a dimmable fluorescent using a cord dimmer, such as the Lutron Credenza. That one is specially made to dim LEDs and fluorescents.

Just wondering if replacing a 75 watt halogen bulb with a 250 watt halogen bulb will create more heat? I am assuming it would? We have a 130V 75 watt E11 Base Light frosted bulb in a ceiling fan/light that doesn't provide enough light and have found a S3109 120V 250-Watt T4.5 E11 Base Light clear Bulb, that we would like to replace it with. Just want to make sure that we are not creating a fire hazard!
