Buying Guide
- 250W infrared bulbs provide strong radiant warmth suitable for bathrooms; consider BR40 vs R40 configurations for heat focus and coverage.
- If you want brighter bathroom lighting plus heat, choose fixtures that combine both, like three-light vanity with heat-capable bulbs.
- Ensure E26 base compatibility and verify enclosure protection against moisture and steam.
- Ceiling-mounted heaters or recessed fixtures require proper clearances. In wet areas, use fixtures rated for damp locations.
- Look for bulbs with longer life ratings to reduce maintenance; consider combined heat-and-light units for efficiency.
FAQ
