Purpose and fit

The Antique Light Bulb Co. EJM MR16 halogen bulb delivers 150 watts at 21 volts for fixtures that require a GX5.3 two-pin base. It suits display, accent or task lighting where a compact MR16 form factor is specified.

Capacity and headroom

The lamp produces 170 lumens at a 3400K colour temperature with a colour rendering index of 100, giving accurate colour reproduction for artwork or retail displays. Rated life is 40 hours, so the bulb is intended for intermittent use rather than continuous operation.

Build integration

The GX5.3 base fits standard low-voltage MR16 sockets without adapters. The 21-volt rating means the fixture must supply the correct voltage; a mismatched transformer will cause immediate failure or reduced output. The short lifespan frees the user from long-term maintenance planning but requires spare units on hand.

Questions about this item

Will the 21-volt MR16 operate correctly in a fixture rated for 21 volts?

Yes, the bulb is specified at 21 volts and 150 watts with a GX5.3 base, matching fixtures built for that exact voltage and pin spacing.

How can I confirm the 3400K colour temperature is correct once installed?

The light should appear a neutral white, and the rated 100 CRI means colours will render naturally under the 170-lumen output.

Does the package include only the 54747 halogen capsule or any extra components?

The box contains the single MR16 halogen bulb with GX5.3 base; no transformer, dimmer or additional hardware is supplied.
