Stage & Studio Halogen Bulb 6 Pack

This GE 43703 pack contains six clear double-ended halogen lamps rated at 300 watts and 120 volts. Each bulb produces 5,950 initial lumens at a 2,950 K colour temperature with a T2.5 ANSI shape and R7s base. The lamps are designed for horizontal burn operation in professional fixtures.

Theatre, TV and photography lighting

The bulbs suit studios, stages and film sets that need crisp white light with excellent colour rendering for talent and sets. They are not intended for general household fixtures, enclosed recessed cans or any socket that does not accept an R7s base and horizontal orientation. Buyers needing dimmable LED alternatives or different base types should look elsewhere.

Sustained output over 2,000 hours

Rated life is 2,000 hours under horizontal burn conditions with near constant lumen maintenance across that period. The 4.68 inch overall length fits standard stage and studio fixtures. Continuous operation at full power delivers stable 5,950 lumen output without the rapid depreciation seen in short-cycle use.

Questions about this item

What fixture base must I already have to install these 43703 lamps?

These lamps require an R7s base; the fixture must accept that double-ended socket for the 120 V 300 W halogen capsule to make proper electrical contact.

Can I run the 43703 bulbs vertically in my older follow-spot housing?

No; the 2000-hour rating applies only to horizontal burn, so operating them vertically in an existing housing will shorten life and may cause premature failure.

How do I confirm each 43703 lamp is performing correctly after installation?

Verify the 2950 K crisp white output and initial 5950 lumen level with a light meter, and ensure the 4.68-inch capsule seats fully in the R7s base without flicker.
