Halogen lights use halogen gas to increase light. Halogen lamps allow the filament to operate at a higher temperature to produce brighter light unlike LED that uses less energy and operates at a lower temperature to but produces brighter light.
Halogen lights can be replaced with LED lights as an upgrade to improve energy sufficiency. In color temperature LED lights have the ability to emit both warm white and cool white colors whereas halogen is limited to warm white color which makes LED lights advantageous in color change for different occasions.
While halogen lamps have a lower average life span, LED lights on the other hand are long lasting.
Replacing halogen with LED saves you money .LED energy consumption is lower than the regular halogen lamps this leads to lower energy costs in terms of electricity.
