Did You Know? ENX, ENX-5, and ENX-7 Overhead Projector Bulb Compatibility Issues
The ENX, ENX-5 and the ENX-7 lamps work in all overhead projectors that call for an ENX lamp. All three lamps are rated to last 75 hours. The difference between them is the voltage used by the lamp, the light output and the lamp life. Compared to the ENX:
ENX-5: approximately 15% fewer lumens, 2% less color and 70-100% longer life
ENX-7: Approximately 25% fewer lumens, 4% less color, and 100-150% longer life
