|Browse a selection of T3 and T4 krypton/xenon light bulbs that are available with either frosted or clear glass envelopes and different type bases. These krypton/xenon lamps can be used in chandeliers, outdoor lighting, sconces, vanity fixtures, portables, ceiling fixtures, and other lighting systems. Krypton/xenon bulbs contain both krypton and xenon gas to increase lamp life, produce a higher lumen output at a lower wattage, and provide a bright white light similar to a halogen bulb.|
- Basic Makeup
Q) What makes a light bulb a krypton/xenon light bulb?
- A) A mixture of krypton and xenon gases has been introduced into the glass envelope of the light bulb.
- Q) Why add a mixture of krypton and xenon gas to the other gases inside the glass envelope of a light bulb?
- A) When compared to similar halogen lamps the krypton/xenon light bulbs have a longer rated life, are a bit cooler to the touch, emit no UV rays, have a wider range of dimmability, and are more energy efficient.
- Q) How are krypton/xenon light bulbs and xenon light bulbs different?
- A) Krypton/xenon lamps contain both krypton and xenon gas while xenon lamps do not contain krypton gas in the glass envelope. Krypton/xenon lamps emit a brighter white light that is similar to halogen lamps whereas xenon lamps emit a light that is slightly warmer in appearance.
- Rated Life
Q) What is the rated life of krypton/xenon light bulbs?
- A) Depending on the conditions under which it is being operated the rated life of a krypton/xenon lamp is expected to be around 3,000 hours.
- Q) What does the term, "rated life", of a light bulb mean?
- A) The "rated life" of a lamp signifies the time at which 50% of a large quantity of these lamps will have burned out. This means that 50% of these lamps will burn out before the "rated life" and 50% will burn out after the "rated life”. The "rated life" does not mean that every one of the lamps will last at least that long.
- Q) Is this definition of "rated life" true for all types of light bulbs or just krypton/xenon light bulbs?
- A) Yes, this is the standard definition of “rated life” for all lamps.
Q) How does a krypton/xenon light bulb create light?
- A) A krypton/xenon light bulb, like an incandescent light bulb, creates light by passing electricity through a filament until the filament reaches the point of “incandescence”, the point at which the filament gives off light in addition to heat.
- Q) Do I have to be concerned about touching a cool krypton/xenon light bulb with my bare hands?
- A) No. Unlike some halogen lamps, krypton/xenon lamps may be handled with bare hands without experiencing premature lamp failure. [Caution: always wait for the xenon lamp to cool down before touching it.]
- Q) Can I replace some of my incandescent or halogen light bulbs with comparable krypton/xenon light bulbs?
- A) Yes, as long as the krypton/xenon lamp has the same wattage rating, the same voltage rating, the same type of base (candelabra, mini-candelabra, double contact bayonet, medium, or double-ended) as the incandescent or halogen lamp, and has a shape and size that can fit into the light fixture in question.
- Q) Are krypton/xenon light bulbs relatively cool to operate?
- A) Krypton/xenon lamps are cooler to the touch than similar halogen lamps but definitely not as cool as fluorescent lamps. Line voltage (120 volts) krypton/xenon lamps operate especially cooler than line voltage halogen lamps, which can become extremely hot.
- Q) Are krypton/xenon light bulbs considered to be energy efficient?
- A) Yes when compared to similar halogen lamps. For example, the 180-watt krypton/xenon double-ended lamp can easily replace the standard 250-watt halogen double-ended light bulb with similar illumination.
- Q) Do krypton/xenon light bulbs require a ballast to operate?
- A) No, krypton/xenon light bulbs, like xenon light bulbs, do not require a ballast to operate.
- Q) Do krypton/xenon light bulbs require a transformer to operate?
- A) No, our krypton/xenon light bulbs are rated at 120 volts (line voltage). Only low voltage lamps rated at 12 volts or 24 volts require a transformer to operate.
- Type of Light
Q) What "kind of light" is given off by krypton/xenon light bulbs?
- A) Krypton/xenon lamps provide light very similar to halogen lamps. Light from halogen lamps is often described as a “crisp, white light”, light that is a bit cooler in appearance than the light coming from a xenon lamp.
- Q) Do krypton/xenon light bulbs provide good color rendition of the objects they are lighting?
- A) Absolutely. Krypton/xenon light bulbs are considered to have a color rendering index (CRI) of 100, which is considered perfect – like the sun.
Q) Are krypton/xenon light bulbs dimmable?
- A) Definitely, all krypton/xenon lamps are dimmable.
- Q) Will dimming a krypton/xenon light bulb reduce the amount of energy it consumes?
- A) Absolutely, just like xenon lamps.
- Q) Will dimming a krypton/xenon light bulb increase its average life?
- A) Yes, dimming increases the rated life of incandescent lamps and krypton/xenon lamps are a type of incandescent lamp.
- Q) What kind of dimmer should be used with krypton/xenon light bulbs?
- A) Since all of our krypton/xenon lamps operate with line voltage (120 volts), they are fully dimmable with a standard line voltage dimmer.
