Description

Ushio brand MR16 halogen special purpose lamp. ANSI EJA. 150 Watts for more power and light. 21 volts for specialty low voltage systems. Low voltage means a smaller fillament, for greater optical control.

Dichroic reflector reflects visible light out the front while letting heat escape out the back, resulting in a cool beam of light

NOTE - this is not a general purpose lamp. Light output is greater and color is brighter than equivalent halogen lamps, but rated life is only 40 hours. Generally used in microscope, dental, and photo curing applications

Full Specs

Brand	Ushio
Model Number	EJA
Energy Used A rating, expressed in watts, to indicate the rate at which a lamp consumes energy. Also known as wattage value.	150 Watts
Volts A measure of "electrical pressure" between two points. The voltage specification of an incandescent lamp is the electrical "pressure" required to drive it at its designed point. The "voltage" of a ballast (e.g. 120 V) refers to the line voltage coming from the power source and is connected to the ballast.	21
Base The end (or ends) of the lamp that fits into the socket.	GU5.3
Bulb Shape The description of the general appearance of a lamp/bulb consists of a letter(s) followed by a number. The letter indicates the shape of the bulb and the number relates to the diameter of the bulb in eighths of an inch. For example, a common household bulb is the A-19. The bulb is "A" shape and the diameter would be nineteen 8ths of an inch, or 2 3/8".	MR-16
Bulb Color The color of the light produced by a bulb	Neutral White
Color Temperature (Kelvin) An expression of the hue of the light emitted, measured in degrees Kelvin. Usually expressed by a four digit number followed by (k), such as 2700k. Higher temperatures indicate whiter, "cooler" colors, while lower temperatures indicate yellower, "warmer" colors. Some common Kelvin temperature benchmarks are 2700k (warm white), 3500k (neutral white), 4100k (cool white), 5000k (bright white), and 6500k (daylight).	3400

Bulb Finish The surface finish of a bulb, which may affect the quality of the light emitted.	Clear
Bulb Technology The technology implemented by the bulb, e.g. incandescent, halogen, LED	Halogen
Average Rated Life (hr) A measurement of the average length of time, between first use and the point when 50% of the lamps tested have stopped functioning, , using an operating cycle of 3 hours on, 20 minutes off.	40
Length (in) Also referred to as "Maximum Overall Length" (MOL). For light bulbs, it measures the length of a light bulb, from the top of the bulb to the bottom of the base or pins and is typically expressed in inches. For light fixtures and ballasts, it applies to the total horizontal length of the item.	1.75
Diameter (in) Light bulbs: a measurement of a bulb's width taken at the widest point of the bulb. Fixtures: the measurement across the widest point of a circular fixture.	2
Dimmable Indicates whether a product can be dimmed in conjunction with a suitable dimmer control.	Yes
Not For Sale In This bulb falls within State-defined sales restrictions for the listed States.	NV, CA & DC
