A 190 W replacement lamp module with housing delivers 4500 hours in standard mode or 15000 hours in economic mode
The VS16971 module delivers a 190W bulb pre‑mounted in its housing, matching the original RLC‑111 specification. It is aimed at owners of compatible ViewSonic projectors who need a direct, new lamp to restore brightness without sourcing separate components.
The assembled bulb‑and‑housing design allows a straightforward swap; no alignment of a bare bulb is required. Most problems arise when the projector’s lamp‑hour counter is not reset after fitting, which can trigger premature shutdown warnings.
In standard mode the lamp is rated for 4500 hours, while economic mode extends the rating to 15000 hours. Output remains stable across long sessions when the projector’s cooling system is clean and the correct mode is selected.
Measured against everything we stock in Replacement Projector Bulbs, at today’s prices. Recalculated every night.

The projector should ignite without flicker and display a steady image; the on-screen lamp timer will begin counting from zero toward 4500 hours in standard mode or 15000 hours in economic mode.
The module includes a new 190W bulb fully assembled in its housing (ViewSonic RLC-111), so no separate bulb or housing purchase is needed for installation.
All versions are built to ISO9001 standards using genuine OEM parts from Philips, Osram, Ushio, Phoenix, Iwasaki or Matsushita; select the OEM version matching your original bulb maker or the compatible version for a lower cost.
