Projector Lamp Prices in 2026: What OEM, Compatible and Bare Lamps Actually Cost
Projector lamps sell in three price tiers for the same fit: the OEM module sold by the projector brand, a compatible module built by an aftermarket manufacturer, and a bare burner with no housing. The OEM module is the most expensive and the bare burner the cheapest, often by a large multiple. The number that actually matters is not the sticker price but the cost per rated hour, and on that measure the gap between tiers narrows considerably — sometimes it reverses.
Prices move with burner supply, freight and exchange rates, so this page explains what drives each tier rather than quoting figures that would be out of date by the time you read them.
The three tiers and what you are paying for
OEM module
Sold under the projector brand's own part number, built to the brand's specification, and warranted by the brand. You are paying for a guaranteed optical match to your chassis, a known burner, and a warranty that is easy to claim against. This is the low-risk option and it is priced accordingly.
Compatible module
Built by an aftermarket manufacturer to fit the same chassis. Quality varies enormously across this tier and that variance is the whole story. A good compatible module uses a genuine Philips, Osram or Ushio burner in a properly moulded housing and performs close to OEM. A poor one uses an unbranded burner, a loosely toleranced housing, and delivers less light for fewer hours.
Bare burner
The arc tube and reflector alone, with no housing. The cheapest per unit by a wide margin, but it has to be transferred into your existing housing. That means handling quartz glass, aligning the burner precisely in the reflector, and reusing a housing that has already been through thousands of thermal cycles. Misalignment costs brightness immediately and can shorten life.
Cost per hour, not cost per lamp
Divide the purchase price by the rated lamp hours and the comparison changes shape. A lamp costing twice as much but rated for twice the hours is the same cost per hour with half the labour — and on a ceiling-mounted projector in a boardroom, the labour of swapping a lamp is not trivial.
Two adjustments worth making to that calculation:
- Rated hours are usually quoted in eco mode. Full brightness typically reduces rated life significantly. Compare like for like.
- Brightness decays across life. A lamp is not equally bright at hour 1 and hour 2,000. If the room needs a certain brightness, effective life is shorter than rated life.

What drives price differences between brands
- Burner wattage. Higher-output burners for large-venue projectors cost more than 200–250 W office lamps.
- Housing complexity. Simple clip-in housings cost less than cage assemblies with integrated filters or cooling ducts.
- Volume. Lamps for widely sold office and classroom projectors are cheaper than lamps for low-volume or discontinued models.
- Age of the model. Lamps for long-discontinued projectors get more expensive as supply dries up, not cheaper.
That last point catches people out. If you run an older fleet, buying a spare while lamps are still readily available is often cheaper than buying one in two years.
When each tier is the right buy
| Situation | Sensible choice |
|---|---|
| Single projector, critical use, in warranty | OEM module |
| School or office fleet, routine replacement | Quality compatible module |
| AV department with tooling and practice | Bare burner |
| Ceiling mount, difficult access | Longest rated life available |

Frequently asked questions
Why are OEM projector lamps so expensive?
You are paying for a guaranteed optical and mechanical match to your chassis, a known branded burner, and a warranty from the projector manufacturer. The physical lamp may be similar to a good compatible; the assurance is what costs.
Are compatible projector lamps worth it?
A quality compatible module using a genuine Philips, Osram or Ushio burner performs close to OEM for considerably less. The risk is variance within the tier, so the supplier matters more than the price.
Should I buy a bare lamp to save money?
Only if you are comfortable transferring a quartz burner into your existing housing and aligning it accurately. Misalignment costs brightness and can shorten life, which erases the saving.
How do I compare projector lamp prices properly?
Divide price by rated hours to get cost per hour, then check whether the rated hours are quoted in eco mode or at full brightness. Add the labour of the swap if the projector is ceiling mounted.
Do lamps for older projectors get cheaper over time?
Usually the opposite. As a projector model is discontinued and stock runs down, its lamps become scarcer and more expensive. Buying a spare while supply is good is often the cheaper decision.
