Performance

	Lamp Power		Lamp power is the wattage of the lamp.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Mean Lumens		Mean lumens is the average lamp output over a designated amount of time, usually 40 to 50 % of rated lamp life. A lumen is the standard international (SI) unit of luminous flux or quantity of light.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Wavelength Range		The range of wavelengths the lamp is designed to emit.  Infrared lamps are designed to emit light in the Near Infrared (.7µm-1.3µm), Middle Infrared (1.3µm-6µm), Far Infrared (6µm-40µm), and Far-Far Infrared (40µm-1000µm).
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
	Color Temperature		Color temperature is a measure of the visual "warmth" or "coolness" of the light from the lamp. The higher the value, the whiter or "cooler" the light appears.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Color Rendering Index		Color rendering index is an indication of a lamp's ability to render object colors in a normal, natural way. A higher number indicates better color appearance. Numbers range from 0 to 100.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Diameter		The diameter of the lamp.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Maximum Overall Length		The maximum overall length of the lamp.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Rated Average Life		Rated average life is the lamp-burning hours to median life expectancy.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Lamp Bases

	Your choices are...
	1" Ribbon Leads		1" ribbon leads.
	4" Leads		4" Leads.
	6" Flex Leads		6" flexible leads.
	2-Pin		2 Pins make the connection for the lamp.
	4-Pin (Circling)		Circling is a four-pin connection.
	Ad medium		Ad medium is halfway between a medium based and a mogul screw base.
	Ad medium Skirted		Ad medium is halfway between a medium based and a mogul screw base. The term "skirted" means that the base flares out at the top.
	Base Restricted Mogul		Movement of the base is restricted. The restricted mogul base is used for many mercury, metal halide, and sodium lamps. It also used for incandescent lamps over 300 W. Lamps requiring more than 200 V are more likely to have a mogul (or larger) base instead of a medium base.
	Bi-Pin T-5		Bi-pin T-5 uses a miniature-sized, two-pin connection.
	Bi-Pin T-8		Bi-pin T-8 uses a small, two-pin connection.
	Bi-Pin T-10		Bi-pin T-10 uses a medium-sized, two-pin connection.
	Bi-Pin T-12		Bi-pin T-12 uses a large, two pin connection.
	Candelabra		Candelabra bases are used mostly for decorative lighting such as chandeliers. 15/32 inch.
	Candelabra Refocus		Used for decorative lighting, chandeliers. 15/32 inch. No screw, refocus.
	Double Contact Bayonet		No screw, two bayonets on bottom make contact.
	Double Contact Bayonet Candelabra		The candelabra base has a double bayonet connection instead of a screw connection.
	Extended Mogul End Prong		Used for most mercury, metal halide, sodium lamps, and also incandescent lamps over 300 watts. Lamps requiring more than 200 volts are more likely to have a mogul (or larger) base rather than a medium base.
