Infographic - Compare Light Sources

You don’t have to be a lighting expert to know that an incandescent light bulb can’t hold a candle to the efficiency of an LED lamp. But it’s a little more difficult to distinguish between the life expectancy of a xenon light versus a halogen light, or to pinpoint which light source is right for your office. That’s where we come in.

Compare Light Sources, text version:

	Fluorescent	Halogen	Incandescent	LED	Xenon	Candle
Operation	When electricity passes through mercury vapor in a glass tube the invisible light given off interacts with the coating in the glass and produces visible light	Similar to incandescent except that a small amount of a halogen gas has been added to the inside of the glass envelope	When electricity passes through a metal filament to the point of “incandescence” the filament gives off light as well as plenty of heat	When electricity passes through  certain diodes (electronic components) they give off light and become a Light Emitting Diodes	Very similar to incandescent except a small amount of xenon gas has been added to the inside of the glass envelope	Cloth wick surrounded by wax has a small burning flame that often “flickers”
	Fluorescent	Halogen	Incandescent	LED	Xenon	Candle
Type of Light	All types of white light (e.g., warm white, cool white, daylight) with good to very good color rendition	Crisp white light with very good color rendition	Yellowish light with good color rendition	Many colors are available including warm white and cool white	Similar to incandescent light only slightly less yellow	Very yellowish light
	Fluorescent	Halogen	Incandescent	LED	Xenon	Candle
Strengths	Gives off a lot of light and is very energy-efficient; newer, compact models can fit some residential fixtures	Good for illuminating art and fitting into small areas; need to be changed less often than incandescent bulbs; can be dimmed; better beam control allows light to be carefully focused	Emits a warm light that flatters pretty much all skin tones; inexpensive to purchase; easily dimmable	Uses very little energy or space; is inexpensive to operate; gives off with very little heat; can last for years	Lasts longer than standard incandescents; can be dimmed; unlike halogen light bulbs the glass can be touched without reducing the life of the light bulb	Flame flicker makes everyone look their best and cannot be duplicated by electric light sources
	Fluorescent	Halogen	Incandescent	LED	Xenon	Candle
Weaknesses	Older versions of fluorescent light bulbs can make you look gray-green; many fluorescent fixtures cannot be dimmed	The light can be too bright for living rooms or some decorative fixtures; light bulbs and fixtures can become very hot; touching glass will shorten the life of the light bulb	Cheaper models burn out quickly; use a lot more energy than fluorescents or halogens; emit a lot of heat	Are not yet widely available for home use and certain types of fixtures can be expensive to purchase; cannot be dimmed	Not very energy-efficient; emit some heat but not as hot as halogen	Fire hazard; candles need to be replaced often to avoid messy half-burned look
	Fluorescent	Halogen	Incandescent	LED	Xenon	Candle
Comments	New fluorescents with new coatings give fluorescent lights a MUCH more flattering glow	Have become increasing popular because of their ability to light well	The “daylight” varieties (with a bluish tint) are closer to outdoor light than typical incandescent light bulbs	Quickly becoming a standard in car dashboards, traffic lights, and taillights; home LEDs often require extra parts to operate	Becoming VERY popular for under cabinet lighting	Almost everyone looks better in candlelight
