Two-pack halogen MR16 bulbs

This twin pack supplies a pair of 150 watt halogen MR16 lamps rated for 21 volt operation. The bulbs are sold new and ready for immediate installation in compatible fixtures. Each unit delivers the focused output expected from a standard MR16 halogen source. The pair covers dual-lamp fittings or provides a ready spare.

Fits 21 volt MR16 sockets only

Installation requires a fixture and transformer that match the 21 volt rating and MR16 base. Mains-voltage or other low-voltage sockets will not work and could damage the lamps. The halogen design produces heat, so the surrounding housing must allow adequate ventilation. Buyers who need dimmable LED alternatives or higher-efficacy light sources should look elsewhere.

Questions about this item

How long will a 150 W halogen MR16 run before the filament fails under continuous use?

At 150 W the filament reaches its design temperature quickly; typical MR16 halogen life is measured in hundreds rather than thousands of hours, so plan for replacement after sustained daily operation.

How much heat does the 21 V 150 W bulb add to a closed fixture after several hours?

Nearly all 150 W input becomes infrared heat, so the fixture and surrounding surface will become very hot — ensure the housing is rated for 150 W and allow generous airflow.
