Acer Projector Lamp Replacement: Model-by-Model Guide

Acer projector lamp part numbers follow the format EC.XXXXX.XXX — for example EC.K1700.001 — and the code is printed on a label on the lamp housing and listed in the projector's specification. Acer uses Philips UHP, Osram P-VIP and Ushio burners depending on the model, and the same burner appears across several different Acer housings, so the part number rather than the burner is what determines fit. Always match the full EC code, including the suffix, because codes differing by one character are genuinely different lamps.

Acer is one of the largest projector brands in US classrooms and small offices, and its lamp range is correspondingly wide. Here is how to navigate it.

Reading an Acer lamp part number

The EC prefix identifies it as an Acer consumable. The middle block identifies the lamp family, and the three-digit suffix identifies the specific variant. That suffix matters: it commonly distinguishes wattage or housing revisions between projectors that otherwise look identical.

The code appears in three places:

• On a label on the lamp module housing itself.
• In the projector's user manual, under consumables or specifications.
• On the Acer support page for your specific projector model.

If you cannot find it, work from the projector model number instead — it is stamped on the underside or rear of the chassis. See finding your projector lamp part number.

Module or bare burner?

Acer lamps are sold both ways. The complete module includes the burner already seated in the Acer housing with its connector and mounting points. A bare lamp is the burner and reflector alone, intended to be transferred into your existing housing.

For most buyers the module is the right choice. Bare burners save money but require transferring quartz glass and aligning it accurately in a reflector that has been heat-cycled for thousands of hours. Our lamp vs bulb vs module guide explains the difference.

Replacing an Acer lamp, step by step

1. Power down and wait. Unplug the projector and let it cool for at least 45 minutes. A hot quartz burner can shatter, and the housing will burn you.
2. Open the lamp door. On most Acer models it is on the side or underneath, held by one or two captive cross-head screws.
3. Release the module. There are usually one or two further screws holding the lamp bracket. Keep them; they are not always supplied with the new lamp.
4. Lift the module straight out by its handle. Do not tilt or force it — the connector is at the back and will resist an angled pull.
5. Fit the new module squarely along its rails until it seats fully. Never touch the quartz glass; skin oil creates a hot spot that shortens lamp life.
6. Refit screws and door, then reconnect power.
7. Reset the lamp timer in the projector menu. This does not affect the lamp, but without it the projector will keep warning you and you will lose track of real hours.

Our step-by-step ceiling mount guide covers the awkward overhead case in more detail, and checking lamp hours covers the reset on each brand.

If the new lamp does not work

The usual causes are a module not fully seated, the lamp door not closed enough to trip its interlock switch, or a timer that has not been reset. Work through them in that order before assuming a faulty lamp — see new projector lamp not working.

Getting more life out of it

• Use eco mode where the room allows. It meaningfully extends rated life.
• Clean the air filter. A blocked filter raises internal temperature, which is the main killer of projector lamps. See projector air filter cleaning.
• Let the fan finish. Do not cut power at the wall immediately after switching off; the cool-down cycle protects the burner.
• Avoid frequent on-off cycling. Each strike stresses the electrodes more than an hour of running.

Frequently asked questions

What is my Acer projector lamp part number?

Acer lamp codes take the form EC.XXXXX.XXX, such as EC.K1700.001. It is printed on the lamp housing label and listed in the projector's manual and on Acer's support page for your model.

Can I use a different Acer lamp in my projector?

Only the exact part number specified for your model. Acer uses the same burners across several housings, so a lamp that looks similar or shares a burner will not necessarily fit or seat correctly.

How long do Acer projector lamps last?

Rated life varies by model and is normally quoted for eco mode. Running at full brightness reduces it significantly. Filter cleanliness and avoiding frequent power cycling have a large effect on what you actually get.

Do I need to reset the lamp timer after replacing the lamp?

Yes. The timer is a counter, not a sensor — it does not detect the new lamp. Resetting it in the projector menu keeps the hour count accurate and stops the replacement warning appearing.

Why did my new Acer lamp fail quickly?

The most common causes are touching the quartz glass during fitting, a blocked air filter raising operating temperature, or a poor-quality burner. Handle the glass only by the housing and clean the filter at the same time.
