In what temperatures do Metal Halide light bulbs operate?

Metal Halide light bulbs are made to go outside. Thus the technology is engineered to operate in a wide range of temperatures. There are no specifics outlined for such but a reasonable range would be from -10 or -20 F up to 120 or 130 F. If you live in an area where the conditions exceed these limits, we recommend you contact the manufacturer to insure your metal halide will perform properly.

What light bulbs are most efficient?

The most efficient light bulbs are LED, Metal Halide and Compact Fluorescent. Between those, you'd need to compare apples to apples. After these, your energy saving or long life halogen light bulbs, then regular halogens and long life incandescents. All in that order. The least efficient light bulbs are incandescent light bulbs. The take the most energy but for most, they produce the quality of light that they are use to and love.

What does Integrated light bulbs mean?

Light Bulbs like compact fluorescent and HID light bulbs contain a gas that needs to be ignited for the bulb to work which is called a starter. They also need a ballast which regulates the voltage of power. Ingegrated bulbs are ones that have that starter and ballast built in the base of the bulb. Non-integrated bulbs have to be used in a ballast that performs those functions for the bulb.

This PAR38 is one of the few metal halide bulbs that is integrated and can be used in a regular socket and doesn't need a special ballast to be used. Philips Integrated PAR38 light bulbs consume up to 3 times less energy than incandescents with the same light and provide the perfect light bulb a retail business or other business wanting to have very clear crisp light.

How do I measure my light bulb?

When measuring a light bulb, manufacturers measure the furthest outside points. The width of the bulb is from the outer edge of the side of the bulb to the other side. Then the length or maximum overall length (mol) is from the very top of your bulb to the very bottom of the base that screws or plugs in.

Can I use a 130 volt light bulb in the place of a 120 volt?

Absolutely. Using 130 volt bulbs is actually a better thing that 120 volt. Voltage is the amount of voltage the bulb can handle when the electricity comes into your home. At one time there were only 120 volt bulbs. Now, 130 volt bulbs are taking over. 130 volt bulbs can take the power surges better than the lower voltage and will last longer as a result.

Now, it's important to know that if you already are using 120 volt bulbs in recessed lighting in a room and you start replacing them with 130 volt bulbs, the 130 volt bulbs might burn slightly dimmer than the 120 volt. Simply because it's on the same circuit as the 120 volt and that will mess with the circutry. It shouldn't shorten the life of the bulb but it's something to consider.
