Low Voltage Halogen Lamps

Low voltage halogen lamps  are used for displays or accents, which is why you frequently come across them in museums, art galleries, retail stores, and the home. The sharp defined beam make these lamps ideal for highlighting anything from sculptures to shoe displays.

Two types of low voltage halogen lamps:

Aluminum Coating
	Thin film of aluminum Reflects light and infrared radiation ie heat forward Hotter than Dichroic coating

Dichroic Coating
	Thin multi-layer non-metallic film Allows heat to pass through, while it reflects light forward Coating quality varies from manufacturer to manufacturer, the lower the quality the faster the coating wears out

Desk Lamps
	Pros Smaller and less expensive than buying a high intensity discharge (HID) for the same job. Whiter light Highly controlled light beam Cons As coating degrad so does light quality Fire hazards If lights don't have glass covers potential of glass shards and UV radiation (if light produces UV rays)
