Extended Product Information

FAQs

Can these bulbs be used outdoors?

Yes, they are suitable for outdoor security floodlights, provided the fixture itself is rated for outdoor weather conditions.

Do I need a special dimmer switch?

These bulbs are compatible with standard trailing-edge or leading-edge dimmers typically used for incandescent and halogen lighting.

Why does the bulb get so hot?

Halogen bulbs operate by heating a filament to high temperatures to produce light; this is normal performance for this technology.

Can I replace an LED bulb with this halogen bulb?

Yes, provided your fixture socket fits a 78mm length and supports the 150W power draw.

What does 2800K mean?

2800K refers to the color temperature of the light, placing it in the 'warm white' spectrum, which appears soft and slightly yellowish.

Troubleshooting

Bulb flickers after installation

Verify that the bulb is fully seated in the spring-loaded terminals and that the contacts are free of debris.

Bulb failed prematurely

Check that you did not touch the glass with bare skin during installation; oils from your fingers create heat-retention spots that can shatter the quartz.

Lamp won't turn on

Confirm the power is reaching the fixture and check that the fixture's internal socket pins are not bent or loose.

Pros and Cons

Pros

Excellent color rendering for accurate visibility
Fully dimmable for versatile lighting control
Provides immediate, flicker-free full brightness
Robust construction suitable for indoor and outdoor fixtures
Convenient 5-pack for cost-effective replacement

Cons

Higher power consumption compared to equivalent LED bulbs

Setup, Compatibility & Care

Installation

Ensure the power source is switched off and the fixture has cooled completely before touching the bulb.
Handle the new bulb using a clean, dry cloth or tissue; skin oils can cause hot spots on the quartz glass, significantly reducing the bulb's lifespan.
Insert one end of the 78mm bulb into the spring-loaded socket and gently push back to seat the other end.
Ensure the bulb is secure and straight before restoring power.

Compatibility

These bulbs are compatible with any fixture designed for a 78mm R7S base. Always verify the fixture's maximum wattage rating to ensure it can safely support a 150W load.

Maintenance

If the bulb surface accumulates dust, clean it gently with a soft, lint-free cloth while the bulb is cold. Never use liquids or harsh cleaners on the glass.
