The bulb or lamp in your projector can make all the difference in the quality of your presentation. Whether it’s in a classroom, conference room or assembly hall, you want the clearest picture possible from whatever type of projector you use. When the light starts to dim and it’s time for a projector replacement bulb, only rely on Original Equipment Manufacturer (OEM) bulbs and housing as these are designed and manufactured specifically for your particular projector. They are the highest quality bulb you can buy and will give you the most hours of presentation.
Why Is it Important to use OEM Lamps?
Projector bulb replacements are also manufactured by outside companies for different brands of projectors. These are called compatible or equivalent projection lamps. Equivalent projector bulbs are manufactured to be exact replicas of OEM lamps, and the housing is made by a third party. Compatible bulbs are low-quality equivalent bulbs. They may work for a while, but they are not manufactured to the same specifications as an OEM bulb.
Equivalent and compatible projector bulbs may work fine for a while, but they are not designed to last as long as an OEM bulb and may not give the same brightness. In addition, the warranty of the projector may require the use of OEM bulbs to remain valid. While many manufacturers may overlook the use of a non-OEM bulb to honor the warranty, if the damage to the projector was caused by the faulty, non-OEM bulb, they may void the warranty.
To make sure you get the right OEM projector bulb replacement and housing, take note of the type you need or keep your guide handy, so when the time comes, you are not in doubt about what type of bulb to purchase. Whether it’s for a front projector, television, smartboard, overhead projector or rear projector, if you take proper care and keep the bulb and housing clean and free of dust, it will have a significantly longer life.
Why Do Airplanes Need So Many Lights?
Airplanes have so many lights all around the craft for safety and to signal actions such as starting the engines or entering a runway. Certain lights indicate to the tower and other planes waiting for takeoff or landing the pilot’s intentions. These aircraft lamps need to have extremely powerful bulbs, so the light can be seen from a distance, whether in the air or on the runway. Certain lights also send the message to the ground crew to vacate the area or when it is safe to approach the aircraft.
The red light on the tip of the left wing as the pilot sits, and the green light on the right wing are navigation lights and indicate to someone on the ground or in the air the direction the aircraft is flying. These lights must be kept turned on from sunset to sunrise.
Anti-collision strobe lights are placed in various positions on the plane such as under the plane, on the wingtips and aft, along with an aft light. Aircraft built after March 11, 1996, must have strobe lights or a rotating beacon that are used when there is poor visibility. There are also giant headlights that are turned on when the plane reaches 10,000 feet before landing. They are very bright and are tilted downwards to enable the pilot to see the runway.
Each one of these lights needs a different type of aircraft light bulb that must never be allowed to become dim to remain compliant with the Aeronautical Information Manual (AIM) and Federal Aviation Administration (FAA) regulations. Most commercial airplanes have a logo light that illuminates the logo on the tail, but this is not required.
