Maintenance

Replacing a lamp, and the three tiers listings blur

A lamp is a consumable with a stated life, and the shelf that sells replacements has three tiers that listings deliberately blur. Knowing which one you are buying is most of the decision, and the model number on the underside of your projector is the only thing that establishes compatibility.

By

The three tiers

Original module — the maker’s bulb in the maker’s housing. Most expensive, no compatibility doubt. Bulb-inside — an original Philips, Osram or Ushio burner in a third-party housing. Usually the sensible purchase, and the OSRAM listing here is that tier. Compatible — neither, and where the variation in life and brightness lives.

Establishing compatibility

By projector model number, exactly, from the label on the underside of the machine. Not by the model of the lamp printed in a forum post, and not by “fits most Epson”.

What to read on the listing

Whether the housing is included, the stated life in hours with its mode — the figure is quoted in eco — and the warranty. Those three separate two listings that otherwise look the same.

While the machine is open

Clean the filter if it has one, and blow the dust off the lens rather than wiping it. The PRINOX kit is the safe option for the optics: no alcohol, no ammonia, because both dissolve the anti-reflective coating, and the damage looks like haze and is permanent.

After fitting

Reset the lamp timer in the projector menu. It does not affect the new lamp, and it is the only way the machine will warn you honestly next time.

Questions people actually ask

Do I need the housing?

It depends what you are replacing. A bare bulb costs less and requires transferring the cage from the old lamp, which is fiddly and entirely doable. A complete module drops in. Listings state which is supplied, and it is worth reading twice.

How do I know my lamp is failing?

Gradual dimming rather than failure, most of the time. A projector that has quietly become less impressive over two years is often a lamp at the end of its stated hours rather than a machine that was overrated.

How do I know the lamp needs replacing?

The projector's counter warns you, and the picture dims. Check the picture mode and filter first, though, since both dim a picture too.

Which lamp do I buy?

One matched to the projector's exact model number. Lamps are model-specific and nothing else is reliable.

Genuine or third party?

A real decision with real trade-offs. Cheaper alternatives vary considerably, and it is worth reading about your specific model.

Do I need to reset anything?

Most projectors need the lamp hours reset after replacement. It takes a moment and is easy to forget.

Why did my lamp not last?

Heat, usually: blocked vents, dirty filters, or unplugging before the cool-down finished. All shorten a lamp's working period.

Is it safe to do myself?

Generally yes, with the projector unplugged and fully cooled, following the maker's instructions. Lamps run extremely hot.

The tool we use ourselves

Chosen your machine? Now buy it at the right price.

Projectors, soundbars and receivers swing by fifty euros or more across the year, and the biggest "discounts" often land at prices the same model sold for six weeks earlier.
