PAR20 (2.5 in. dia.)

PAR20 bulbs are screw-in bulbs 2.5 inches in diameter. Toshibas tend to have lower costs per lumen. Halcos tend to be the brightest, and Bulbrites are waterproof. They all have great color because they use top-of-the-line emitters. The dimmable bulbs dim beautifully if you use the dimmers we recommend for each bulb.
