Extended Product Information

FAQs

Can I replace my LED bulbs with these halogen ones?

Yes, provided your fixture supports the 35W power draw and the MR11 base type, though you will notice higher heat and energy use.

Are these bulbs dimmable?

Yes, halogen bulbs are inherently compatible with standard incandescent and halogen-rated dimmer switches.

Why shouldn't I touch the glass with my bare hands?

Skin oils leave residue that creates uneven heating on the quartz glass, which can lead to the bulb shattering or burning out early.

What does the MR11 designation mean?

MR stands for 'Multifaceted Reflector', and 11 indicates the diameter of the bulb face in eighths of an inch (11/8 inches).

How do I safely dispose of used halogen bulbs?

Halogen bulbs do not contain mercury and can generally be disposed of with regular household waste, but check your local recycling regulations.

Troubleshooting

Bulb flickers after installation

Ensure the pins are fully seated in the socket and the transformer is providing the correct constant voltage.

Bulb turns off unexpectedly

This may indicate the bulb is overheating due to an enclosed fixture; ensure proper ventilation or replace the bulb if the filament has failed.

Pros and Cons

Pros

  • Provides excellent color rendering for natural-looking light
  • Instant full brightness with no flickering
  • Cost-effective bulk pack for maintenance
  • Small form factor fits into discreet, low-profile fixtures

Cons

  • Higher energy consumption compared to LED bulbs
  • Generates significant heat during operation
  • Shorter operational lifespan than modern solid-state lighting

Setup, Compatibility & Care

Installing these bulbs is straightforward, but it requires caution due to the delicate nature of halogen filaments. Always ensure the light fixture is switched off and has cooled completely before touching the bulb. When handling, avoid touching the glass directly with bare fingers, as oils from your skin can cause hot spots that lead to premature bulb failure; use a clean, dry cloth or a glove during installation. Ensure your fixture's transformer matches the voltage requirements for MR11 lamps to avoid flickering or instability. For maintenance, periodically dust the fixture housing to prevent dust accumulation near the base of the bulb.
