Jaspertronics 24B18012 Auto Iris Module

The Jaspertronics 24B18012 is a new Auto Iris module built for the NEC NP 550W projector. It replaces the original dynamic iris assembly to restore automatic aperture control. The unit weighs 4.0000 and carries part number 24B18012 for exact identification. Installing it returns the projector to its intended contrast performance.

Who This Fits and Who It Does Not

This part suits technicians servicing an NEC NP 550W that has lost dynamic iris function or shows aperture errors. It is not for owners of other NEC models or different projector brands because the mechanical and electrical interface is specific to the 550W series. Buyers needing a complete lamp housing or colour wheel should look elsewhere.

Deciding Specification — Part Number 24B18012

The only specification that confirms fitment is the part number 24B18012 matching the projector service manual. Verify that number on the existing assembly or in the official documentation before ordering. No other dimension or rating in the data determines compatibility.

Questions about this item

How long does the 24B18012 Auto Iris last before the projected image dims noticeably?

The Auto Iris is a light-control mechanism, not the lamp itself, so it does not have a rated hour limit; brightness decay depends on the separate projection lamp installed in the NP 550W.

Does the 24B18012 Auto Iris add audible fan noise or extra heat during all-day projection?

The iris mechanism operates silently inside the optical path and draws negligible power, so it does not increase fan speed or chassis temperature during extended use.

Must the NEC NP 550W projector already be installed and working to fit the 24B18012 Auto Iris?

Yes, the iris is an internal component for the NP 550W; you need the projector chassis, power supply and a compatible projection lamp already in place before installation.
