Halogen Lamp Vs Incandescent. Halogen bulbs have a higher efficiency than incandescent bulbs. This means for the usage up to the 15000 hours you need up 14 incandescent bulbs 2 Halogen bulbs but only 1 LED bulb is needed for the usage.
A typical halogen lamp has an efficiency of around 3 while a fluorescent lamp has anywhere between 10 and 15. Halogen bulbs are extremely sensitive to skin oils which can cause them to malfunction or burst. So to reach a brightness of 800 lumens incandescent light bulbs will require 60 watts to power the light.
The longer they burn the more tungsten soot is deposited on the inside of the bulb.
Halogen bulbs have a fragile quartz envelope and brittle filament wire. This process requires incandescent bulb filaments to be heated less than optimally to give the bulb a reasonable life. An incandescent light bulb has argon gas in it. I notice that they make halogen PAR lamps in addition to incandescentFor example these two are the same wattagebeam anglelamp lifebrand however the halogen lamp has 6000 more centerbeam candlepower sadly they dont both have lumens in the specsheets.
