Metal Halide Light Bulbs

Blown Tubular
Replace the metal-halide light bulbs in your fixture.
Bulbs for open fixtures have a strong outer shell to keep them from shattering if they fail.
Bulbs with an EX39 base can also be used in E39 sockets.
Pulse-start bulbs restart nearly twice as fast as probe-start bulbs.
Bulbs that cannot be sold to Canada exceed local regulatory limits on mercury content.
