Buying Guide: Key Purchase Considerations
- Fixture compatibility: Confirm the diffuser diameter (commonly 6″ or 6.3″/160 mm) and whether your trim style allows diffusers to sit flush without obstructing the bulb.
- Diffusion quality: Decide between opaque, semi-transparent, and frosted finishes based on desired glare reduction and brightness balance.
- Installation type: Stick-on vs. screw-in or taped diffusers; renters typically prefer stick-on or magnetic options for ease of removal.
- Heat tolerance: Ensure materials resist warping or discoloration in proximity to high-output bulbs.
- Aesthetics: Choose a color and texture that harmonizes with existing fixtures and room decor.
