Open Fixture Warning

Unless otherwise stated, all non-enclosed halogen lamps carry the following warning, “A suitable protective shield, screening technique, or both must be used to protect people and surroundings from the possibility of a lamp shattering and from possible ultraviolet radiation”. Enclosed halogen lamps include PAR and BR lamps, “A”, T10 Double Envelope, and BT15 lamps, Lensed MR11 and MR16 lamps, and BallLites.

Rated Life

There is a common misconception that the “Rated Life” of a halogen lamp is a measure of how long the lamp should burn, this is not true. The rated life of a lamp is the point where 50% of the bulbs have burned out, and 50% are still burning, under laboratory conditions. For example, the S4968 (90PAR/CAP/FL) is rated at 2500 hours, this means, some will burn out at 1250 hours, some will last 3750 hours, but ½ will still be burning at 2500 hours, under laboratory conditions. Since halogen PAR lamps are notoriously susceptible to vibration related failures, their rated life my not be accurate in real life circumstances, including high vibration areas such as industrial applications.

Halogen Notes

1 Krypton/Xenon filled lamps provide bright white light similar to Halogen, without a UV hazard. These lamps are fully dimmable without performance loss.

2 Extra tall lamp, with a porcelain spacer designed to create distance between the heat of the filament and the fixture socket. These lamps are primarily used in high-end European import fixtures.

3 Commercial grade product.

4 Suitable for use in unshielded fixtures. Consult most recent luminaire standards for your area to determine luminaire requirements.

5 These lamps feature a frosted reflector and frosted integral cover glass, designed for decorative glass pendant fixtures. They provide light in all directions, without the striations of backlight color common to MR16 lamps.

6 Features an aluminized reflector, creating consistent color over the life of the lamp. Heat is transmitted out the front of the lamp.

7 Features a hard coated dichroic reflector, creating consistent color over the life of the lamp. Heat is transmitted through the back of the reflector.

8 Features MR16 IR technology, increasing light output, or saving energy. The hard coated dichroic reflector creates consistent color over the life of the lamp. Heat is transmitted through the back of the reflector.

9 High Performance PAR lamps, feature a spiral reflector/lens system providing a smoother uniform beam pattern, with superior beam control and sharp cutoff of light.

10 Primarily used in automotive and linear lighting applications.

11 Primarily used in automotive applications. Also used in Tizio desk lamps manufactured prior to 1993.
