SMART Board Projector Bulbs: UF55, UF65, UF70 and V30 Replacements

A SMART Board does not contain a lamp. The lamp is in the short-throw projector mounted on the arm above the board, and that projector is a separate unit with its own model number and its own lamp part. To order the right bulb you need the projector's model - typically a UF or V series unit such as UF55, UF65, UF70 or V30 - not the board's model. The projector label is on the chassis itself, usually on the top or side facing the wall.

Which projector is on your board?

SMART Board systems pair an interactive whiteboard with a short-throw projector on a wall arm. The board and the projector were sold together but are separate products, and over a board's life the projector may have been replaced with a different model.

The model number is printed on a label on the projector chassis. On an arm mount this usually faces the wall or the ceiling, so you will need to look up at it from below or use a phone camera held above it.

Common families you will encounter in US classrooms:

  • UF series - UF45, UF55, UF65, UF70, UF75 and variants. The long-serving short-throw line found on most SMART Board 600 and 800 series installations.
  • V series - V25, V30 and variants, used on later systems
  • Third-party projectors - many districts have replaced an original projector with a generic short-throw unit on the same arm. If the label is not a SMART part number, order against whatever brand it actually is.

Lamp parts differ across these families and sometimes between variants of the same number, so confirm the exact model before ordering. Our cross-reference guide covers finding equivalents.

The lamp hatch on an arm-mounted short-throw projector usually opens downward, which is convenient but means working overhead.

Why short-throw lamps work harder

Short-throw projectors sit close to the board and use aggressive optics to produce a large image from a short distance. That has consequences for lamp life:

  • The optical path is more demanding, so these units often run the lamp at higher power than a long-throw projector producing the same image size
  • Arm mounts put the projector close to the ceiling where air is warmest, and often in a dusty classroom environment
  • Classroom duty is heavy - six or more hours a day through term time

The practical result is that classroom short-throw lamps frequently reach end of life faster than the same lamp would in a conference room. Budget for it rather than being surprised.

Fitting a lamp on an arm mount

The job is straightforward but you are working overhead, which changes the safety picture.

  1. Power off and let it cool - a short-throw lamp needs a full cooling cycle plus time. Twenty to thirty minutes minimum. The burner is at very high pressure when hot.
  2. Isolate properly - unplug rather than relying on standby
  3. Use a proper step platform - not a chair, not a desk. You need both hands free and stable footing.
  4. Open the lamp hatch - usually one or two captive screws on the underside
  5. Withdraw the old module by its cage handle - never touch the quartz
  6. Insert the new module squarely and make sure it seats fully before tightening
  7. Reset the lamp timer - the projector will keep warning until you do, and the counter is how you track the next replacement

Before you order a lamp

Classroom projectors fill with chalk dust, marker dust and general classroom debris faster than almost any other installation. A clogged air filter dims the image and causes the projector to throttle lamp power, which looks exactly like a dying lamp.

Clean the filter and look again before ordering. See air filter cleaning and dim image diagnosis. On a fleet of classroom units this single habit saves a meaningful number of unnecessary lamp purchases every year.

Buying for a school or district

If you maintain more than a handful of boards, standardise. Audit which projector models you actually have, keep a small stock of the common lamps so a failure does not take a classroom out for a week, and order in bulk against a purchase order. Our guide to buying projector lamps for a school district covers standardising part numbers and POs.

Frequently asked questions

What bulb does a SMART Board use?

The board itself has no bulb. The lamp is in the short-throw projector mounted above it, so the part you need is determined by that projector's model number - a UF or V series unit in most cases - not by the board model.

How do I find my SMART Board projector model?

Look for a label on the projector chassis itself, usually facing the wall or ceiling on an arm mount. Holding a phone camera above it is the easiest way to read it from the floor.

Why do classroom projector lamps fail so quickly?

Heavy daily duty through term time, mounting close to the ceiling where air is warmest, and a dusty classroom environment that clogs filters. Short-throw optics also often run the lamp at higher power than a long-throw unit.

Can I replace a SMART Board projector lamp myself?

Yes. It is a few captive screws and a module that lifts out. Let the projector cool fully first, unplug it, use a proper step platform rather than furniture, handle the module by its cage, and reset the lamp timer afterwards.

Do I need to reset the lamp timer?

Yes. The projector will keep displaying lamp warnings until the counter is reset, and the counter is how you know when the next replacement is due.

My SMART Board image is dim - is it the lamp?

Clean the air filter first. Classroom projectors clog quickly with chalk and marker dust, and a restricted filter makes the projector throttle lamp power, producing exactly the same symptom as a worn lamp.

Finding your lamp

Lamps Authority stocks SMART Board projector lamps and short-throw classroom lamps across the major families, in OEM and compatible options. Send us the projector model from the chassis label and we will confirm the correct part.
