Save Money Use Projector Bulbs

Halogen lights have become popular as overhead projector lights.

Here are the characteristics of the projector bulbs that you should consider in purchasing one. The projector bulb comes in many designs, brand names, models, wattage, and voltage. To identify whether the projector bulbs would fit your projector equipment, make sure to learn your projector bulbs before purchasing. These bulbs have been used in:

  • Business presentations
  • School reporting
  • Home-based cinema

1 Type and Shape

Check the base and note its type and shape. Make sure you know the brand and model number of the projector bulbs for your projector – they should be listed in the user manual. If you happen to have lost your user manual, try the company website – they likely offer for download the user manuals that you can print off. This would ensure you don’t go to the store and end up coming back with an incompatible bulb. If you are not aware of the brand, describe the shape of the projector bulb’s base to the attendant at the light store. You could specify by telling the assistant about the shape of the bulb itself.

2 Size Matters

The size of the glass bulb is important. Basically, projector bulbs differ in the sizes of the bulbs’ envelope or casing. The size of the projector bulbs would distinguish your bulb purchase if it is a foreign brand if your projector is used in movie projectors or for slide show projectors alone.

4 Knowing Is Half The Battle

The tungsten filament is a wire that reacts to the heat that occurs when the lamp is turned on. The shape of the filament would help you ask for the exact model or projector bulbs. Since each model makes use of varieties of wires and places the wire in different locations on the bulb, it would be easier for you to break down your choices for your projector bulbs’ purchase.

4 The voltage and wattage

These items determine the overall output of the projector bulbs. The projector bulb that gives out brighter light does not necessarily mean that the wattage is higher than the bulb that produces a dimmer light. Make sure that you are aware of the consuming voltage and wattage of your projector bulbs.


All of the bulbs that are purchased for projectors are coded into three letters (e.g. ELH, DEK). These letters are assigned to all models that have the same filament reactivity, wattage, and voltage. Since the material of the glass base does not have anything to do with the codes, you could choose your own style and could still purchase the exact bulb needed. These codes have no connection with the brand of the projector bulbs. This is done because choosing the perfect projector bulbs is vital in the handling of the projector, the bulb manufacturers follow a coding for their customers to purchase easily and avoid confusion. Knowing this three-letter code would be an advantage for you and the assistant at the store.
