6 Tips for a longer lamp life: - Never touch the lamp - use a cloth. - Never touch the glass - use gloves. - Keep the air filter clean - keeps the lamp cool. - Never switch off the projector by disconnecting the power. Use the normal procedure to secure proper cool down. - Do not create vibrations or move the lamp when it is warm - it's very fragile. - On projectors with hi/low mode use the low when possible.
