Halogen lights have become popular as an overhead projector
light. These projector bulbs provide high-intensity light
that gives the presentation better lighting and dimming that
ensure positive image precision. Here are the characteristics
of the projector bulbs that you should consider in purchasing
one. The projector bulb comes in many design, brand names,
model, wattage and voltage. To identify whether the projector
bulbs would fit your projector equipment, make sure learn
your projector bulbs before purchasing.
These bulbs have been used in:
- Business presentations
- School reporting
- Home-based cinema
- Type and Shape
Check the base and note its type and shape. Make sure
you know what 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
incompatable bulb. If you are not aware of the brand, describe
the shape of the projector bulbs base to the attendant at
the light store. You could specify by telling the assistant
about the shape of the bulb itself.
- 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 projector alone.
- 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.
- 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.
Note:
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 costumers to purchase
easily and avoid confusion. Knowing this three letter code
would be an advantage for you and the assistant at the store.
- It is advisable to purchase a lower-powered projector
bulb.
- Bulbs last up to 2,000 to 4,000 hours, depending on the
usage amount of the projector .
- Projector bulbs are made up of halogen lights.
