This instructional video by Scuba**** explains the difference between the two major types of lights. They are the Halogen (Xeon) and LED. The Halogen has a single glass bulb just like any other light we are used to seeing and the LED light has a diode with no glass involved. The significant difference between the two is that the LED is much more durable and the light is a different spectrum. It is more of a white light unlike the halogen that has a yellow light. The LED also has a longer burning time than the Halogen bulb too. The major advantage to an LED light is the amount of battery life you get. If you change your batteries three times with LED light you will end up changing your batteries nine times with halogen lights. Although the LED is about three times as much, in the long run you will save more money on batteries and bulbs.
