ViewSonic PG705HD Replacement Lamp

The ViewSonic PG705HD RLC-117 projector lamp is a complete module with a 310W bulb pre-assembled in its housing. It is designed for users who need a direct, ready-to-install replacement for a ViewSonic projector. No separate bulb handling or alignment is required.

Practical Lamp Life Limits

Standard operation delivers a rated life of 4000 hours. Switching to economic mode extends the usable cycle to 15000 hours, reducing the frequency of replacements. Brightness will gradually decline as the lamp approaches these limits, and the projector will eventually indicate that a new module is needed.

Straightforward Installation and Common Issues

The fully assembled housing allows a quick swap without tools in most ViewSonic models. Problems typically arise if the lamp door interlock switch is not fully engaged after fitting, which prevents the projector from powering on. Resetting the lamp timer in the menu is essential to track the new module's hours accurately.

Each lamp is built to ISO9001 quality standards, which cap consistency of beam performance, ignition, voltage, appearance, connections and run-time.
