For example, a PAR30 lamp is approximately 3.75 inches in diameter. Similarly, the diameter in millimeters can be found by multiplying the PAR designation by 3.175. For example, a PAR16 lamp is approximately 50.8 mm in diameter.
BulbAmerica offers this great selection of PAR20, BR20 and R20 LED bulbs for homeowners who want to combine convenience, affordability and efficiency in their lighting choices. There are many areas of the home where these bulb types come in handy, which is why this collection makes it easy to stock up on the bulbs you need. With parabolic aluminized reflector (PAR20) LED bulbs, you can maximize the brightness in a space with directed lighting. Bulged reflector (BR20) LED bulbs cast a wide beam that's perfect for can lights; this style of bulb is also known as a reflector (R20) bulb.

The difference between PAR and R / BRVS.PAR 20, 30 and 38 and BR (or R) 20, 30 and 40 despite their similar names are quite different. Though they bear some similarities, understanding their differences will help you make better decisions about which one of these bulbs works best for your needs. They both share almost all of the same features that come with LED Light Bulbs, and therefore you only need to know the following difference between the two types.R (Reflector) / BR (for bulged reflector) bulbs are lamps with “wide flood” beam angles, which means that they provide more than a 45° (typically 120°) angle when lighting an area.

Use BR bulbs when a broad pattern of ambient light is needed such as down a hallway or over a kitchen countertop. BR bulbs also work best in recessed downlights or 'pot lights' as they provide the best wide angle illumination.Shop EarthLED.com's Full Selection of R/BR Series Bulbs By Diameter Below: PAR (short for Parabolic Aluminized Reflector) bulbs are lamps with 'spot light' features, meaning that they provide a beam spread that is typically lower than 45°. Use PAR bulbs when attempting to put a focused beam of light on an object such as in track lighting or illuminating artwork. PAR spot lights also work great as outdoor security lighting.Shop EarthLED.com's Full Selection of R/BR Series Bulbs By Diameter Here: Share this post. As you explain that BR bulbs have a wider spread than PAR bulbs, why do you say “PAR spot lights work great as outdoor security lighting.”?1) Couldn’t it be beneficial to shine light on a broader area for security?2) If the reasoning is that PAR 35 may have a narrow spread, but illuminates out to a farther distance, this doesn’t make sense to me because: First, the ideal spread and distance of security could be different for different situations, couldn’t it? Secondly, if the distance was the factor it would seem that could partially be mitigated by using a higher wattage LED, while still have the benefit of broader coverage and therefore possibly less total bulbs needed.3) If the reason is that one tends to be more weather proof or rugged, we don’t know that because the post doesn’t mention it.
