Product Identity

The Ushio 1000977 JCV120V-400WGSNF is a 120V halogen bulb rated at 400W with an E11 screw base. It delivers 7850 lumens at a warm 2950K colour temperature and offers a rated life of 2000 hours. This single-ended lamp suits residential or light-commercial fixtures that require high-output halogen illumination.

Replacement Guidance

It replaces an existing JCV120V-400WGSNF or equivalent 400W E11 halogen lamp when output has dropped or the filament has failed. The jump is worth it when a fixture demands the full 7850 lumen level and the 2950K warm tone matches the surrounding lighting scheme. Buyers who need a lower wattage, a different base type, or a cooler colour temperature should look elsewhere.

Installation Notes

Installation is straightforward: ensure the power is off, insert the E11 base into the matching socket, and twist until seated. Handle the quartz envelope with clean gloves or a cloth to avoid oil contamination that can cause hot spots and early failure. Verify the fixture is rated for 400W at 120V and provides adequate ventilation for the heat produced.

Questions about this item

Does the E11 screw base fit my existing socket?

The bulb uses an E11 screw base, so it will fit any standard E11 socket rated for 120V.

How do I install the JCV120V-400WGSNF without shortening its life?

Wear clean gloves when handling the quartz envelope; skin oils create hot spots that reduce the rated 2000-hour life.

When should I plan to replace this 400W halogen bulb?

Expect roughly 2000 hours of operation before the lumen output drops below the rated 7850 lumens at 2950K.
