The halogen cycle increases the lifetime of the bulb and prevents its darkening by redepositing tungsten from the inside of the bulb again onto the filament. The halogen lamp can function its filament at a higher temperature than a standard gasoline crammed lamp of comparable energy with out loss of operating life. Such bulbs are much smaller than normal incandescent bulbs, and are widely used where intense illumination is needed in a limited space. Fiber-optic lamps for optical microscopy is one typical utility.

Gentle bulbs are in …
