NEC projector bulbs are one of the replaceable parts of LCD projectors. While older models can be of the halogen type, most LCD projector bulbs today are metal halide that gives off a whiter glow. A metal halide bulb is about four times the price of a halogen bulb but has a much longer lamp life. Every NEC projector bulb has a specific lamp life which indicates the average expected life span of your projector bulb.

When your NEC projector bulb begins to grow dimmer, it may be time to change your lamp. Changing LCD projector bulbs can be very simple. However, remember that the lamp housing and glass are fragile. Also, use a cloth or tissue to hold the bulb during replacement. Be careful so as not to directly touch the lamp with your fingers to keep unwanted oils from getting onto the NEC projector bulb. The oil may cause the bulb to burn out or burst prematurely.

With proper care, you can make your NEC projector bulb last longer. Lamps operated under normal conditions tend to last longer and maximize their lamp life. Normal conditions refer to no more than three to five hours of daily operation in a relatively dust-free environment. LCD projector lamps that are continuously used for long hours on end are most likely to fail before the indicated lamp life. Handled properly, metal halide LCD projector bulbs can last as much as thousand of hours.

LCD projector lamps do not come cheap and with good reasons. They are extremely complicated instruments producing amazing brightness. Assembly of projector lamps is also complex and with limited supplies. It may even prove to be a challenge to even find a replacement projector lamp for some projector models. Hence, you might want to consider purchasing a spare NEC projector bulb when you procure a projector. It will definitely come in handy during emergencies and save you a lot of trouble in case stock is unavailable when you need a replacement.
