Replacement Lamp for ViewSonic Projector PJ503D.
Tips on proper lamp care:
1. Do not handle lamp without gloves. Oil from hands and fingers can result in premature lamp failure.
2. Keep projector air filters clean. Overheating can cause lamp failure.
3. Hot lamps are very fragile. Shock and vibration applied to hot lamps can break them.
4. Do not turn projector on and off too frequently.
5. Some projectors offer "low lamp" or "economy mode" options. Use these whenever possible.
