Halogen bulb for projection and fibre optics

The Platinum EJA is a 150 W halogen lamp rated at 21 V. It delivers 354 lumens at a 3400 K colour temperature with a CRI of 100. The GX 5.3 bi-pin base fits compatible MR16 sockets. Designed for projection, fibre-optic and colour-printer applications.

Replaces worn EJA lamps in existing fixtures

Swapping in a fresh unit restores full 354 lumen output and 3400 K colour accuracy when the old lamp dims or fails. The 40-hour rated life means the change is worthwhile for intensive projection sessions or critical colour-printing runs. Not suited for general room lighting or fixtures needing longer service intervals.

Fits MR16 sockets with GX 5.3 base

The bi-pin base slots directly into compatible MR16 holders without adapters. The 21 V rating requires a matching transformer or driver; the lamp itself frees no additional space and adds no cooling requirements beyond the fixture's original design. Ensure the power supply delivers 21 V before installation.

Questions about this item

What base does the GX5.3 bi-pin require for mounting?

The bulb uses a GX5.3 bi-pin base that pushes into a matching MR16 socket; align the two pins and press firmly until seated.

How is the 150W halogen bulb installed without shortening its 40-hour life?

Handle the quartz envelope only with clean gloves or cloth; skin oils create hot spots that cause early failure.

When should the 354-lumen lamp be replaced in a projection or fiber-optic system?

Replace after approximately 40 hours of operation or when output drops noticeably, as the rated life is 40 hours.
