When it comes to new lighting innovation, GE is one manufacturer that you
can't rule out in this area. Metal halide is still a strong contender in
the game of saving energy over older forms of lighting. What makes it most
desirable is the white light it gives off and the great reduction of
electricity. GE PulseArc metal halide lamps are among that new group of
lighting that most people understand as pulse start metal halides. It's
becoming the specifiers choice to get improved light control while saving
energy. The technology involved in pulse start metal halide lighting is similar to fluorescent
lighting. An arc is established between two electrodes in a gas-filled tube
which causes a special vapor to produce the light you see. Unlike fluorescent
bulbs, this light does not need a coating of phosphors in order to produce the
light, the light comes from the arc itself and creates a tremendous amount of
light. In the broader category of HID lighting, these are the ones you see with
the bright, white color in security, warehouse, parking lot or on the freeway.
One of the chief benefits of GE PulseArc metal halide light bulbs are the
gains in energy efficiency over the standard product. These lamps have more lumens per watt than the standard variety, making it more energy
efficient. Sometimes a 300 watt pulse lamp can replace a 400 watt
standard with no light loss. So in applications like production facilities or
warehouse lighting it means more electrical cost savings. Another key
feature is that these bulbs will last a very long time and will produce more
usable light over that time. The PulseArc metal halide has a faster restrike if it
goes out, that means the lights come on sooner after a shutdown. The average life of a
standard model is typically about 24,000 hours. Compare this to a classic metal
halide
bulb, which has an average life of about 20,000 hours. It is easy to see the
energy savings (thus cost savings) that these bulbs provide. They save energy
while reducing maintenance costs because of their extra long life.
Some people wonder about the color of these light bulbs. Is there a
color shift from different manufacturers? The answer is yes that there can
be a different color between manufacturers and various lots although pulse start
bulbs have less color shift than the older standard lamps. The
Sylvania and GE brands tend to be whiter and more true in color while the
Philips is a warmer color almost having a yellow appearance. If color is a
very important thing to your operation, then you may want to consider using
the Sylvania brand instead. Be aware that color can shift over
time in use and the only way to get back to the original color is to replace the
lamp. It's sometimes a sign of end of lamp life. In most architectural specifications,
metal halide is becoming the HID lamp of choice for almost all applications.
With the advent of more efficient metal halide lamps, other types of bulbs are
being specified less often.
The most common varieties of GE PulseArc metal halide light bulbs are
as follows: MVR300, MVR320, MVR350 and MVR400. The number in these codes
pertains to the wattage of each lamp. They are usually followed by a PS if it's
a pulse start lamp. We
have a large inventory of these lamps for nearly every type of
light fixture in the field. If you need help identifying a bulb, our customer service representatives can help you determine what you have.
