KNOLL HDP420 Lamp / Bulb Lamp part number: LP32

For your KNOLL HDP420 projector, you can choose from: lamps with housing or bare bulbs from original and generic manufacturers...

If you prefer an easy replacement process, buy a lamp with housing.
Alternatively, choose a bare bulb without housing if you already have experience with replacing bare bulbs and are willing to deal with the more challenging replacement process.
If you do not want to compromise on projection quality and reliability, choose an original manufacturer lamp.
If you prefer a cheaper option and projection quality and reliability are not your top priorities, buy a generic lamp.

Easy replacement process for everyone

All you need to do is loosen a few screws in the projector, remove the entire lamp housing, and replace it with the new one. You can choose from 2 lamp options - original or generic.

Generic lamp with housing
The KNOLL HDP420 generic lamp with housing includes generic plastic housing and a generic bulb from an authorised manufacturer of generic lamps. It is a cheaper solution recommended for in-home use, where projection quality and reliability are not as crucial. Even though generic lamps are not necessarily of the same quality as original manufacturer lamps, their price is nevertheless very attractive.

More challenging lamp replacement process recommended only for the manually skilled

Replacing a bare bulb in the original projector lamp housing is more challenging than replacing the entire lamp housing. We only offer this option as an original bare bulb lamp without housing.

Bare bulb options

Original lamp without housing
The original KNOLL HDP420 lamp is a bare bulb from one of the OEM manufacturers (Osram P-VIP, Philips UHP, Ushio, Matsushita, Iwasaki HSCR) and is designed to replace the lamp in your existing lamp housing. This solution is cheaper than a lamp with housing, although it requires a certain amount of manual skills. This option is recommended for customers who already have some experience with bare bulb replacement.
