Parabolic aluminized reflector (PAR) 38 LED bulbs control light more precisely. They produce about four times the concentrated light intensity of general service A shape incandescents, and are used in recessed and track lighting. Like all light bulbs, the 30 value represents the diameter of the bulb in 1⁄8 of an inch. Therefore, PAR 38 is 4.75 inches in diameter.
Since new PAR38 bulbs incorporate LED technology, they are more efficient than standard halogen or incandescent bulbs, meaning they use less energy and last longer. PAR38 light bulbs also emit significantly less heat than other options, which helps reduce the overall heat in an area and the AC needed to keep it cool. PAR38 LED bulbs also have multiple color temperature and beam angle options available as well, unlike halogen models that only come in 3000K.
- 2700K (Warm White)
- 3000K (Soft White)
- 3500K (Neutral White)
- 4000K (Cool White)
- 5000K (Daylight)
- Narrow Spot: 10 degree or less beam angle
- Spot: 15 degree beam angle
- Narrow Flood: 25 degree beam angle
- Flood: 36 degree beam angle
- Wide Flood: 50 degree or greater beam angle
PAR38 LED light bulbs are typically used in large recessed can fixtures, outdoor flood lights and landscaping fixtures. Keep in mind if your going to be using them in an outdoor application, make sure the PAR38 is rated for wet location use or for enclosed fixtures so they are protected from the weather.
