Buying Guide

Match the PAR20 form and E26 base

Confirm your recessed fixture accepts PAR20 bulbs and a standard E26 screw base to ensure physical fit and safe installation

Check wattage vs lumen output

Compare watt ratings (e.g., 39W–50W) against lumen numbers like 600 lm to balance brightness needs with fixture heat limits

Prefer dimmable bulbs for adjustable lighting

Choose dimmable halogen PAR20s when your recessed lights are on a dimmer circuit to maintain smooth dimming performance

Consider color temperature for ambiance

Select warm white (around 2800K) for cozy residential lighting or cooler tones for task-oriented spaces

Compare pack sizes for value

Evaluate single bulbs versus multi-packs (6–9 pack options) to lower per-bulb cost when outfitting multiple fixtures
