2. Step 1 – Obtain Parts Overhead Projector LCD Screen Fan

3. Overhead Projector Specs… Brightness – dependent on wattage of internal lamp. –Example: 400W ~ 3,500 ANSI Lumens! (a normal digital projector is ~1100 Lumens) Type of Bulb –Halogen (less expensive to replace, 400W) –HQI (more expensive to replace, 600W) Recommended Projector: Liesegang OHP 2510
