PAR20-18 12V LED Flood Lamp with 18 LEDs
These LED flood lights are made with very bright 12,000 mcd white LED's PAR-type glass floodlight housings. The 18 LED lamp makes a great reading light if you are within 3 to 4 feet. The 45 LED lamp is extremely bright and easy to read under from 5 to 6 feet away. They have an expected life of 10 years or more and carry a 2 year warranty.
The most common measure of light output is the lumen. Lumens measure how much light actually falls on a surface. The unit of measure commonly used to describe LED intensity is the millicandela or mcd. 1000 mcd = 1 candela. Candelas measure how much light is produced as measured at the light source. Since lumens and candelas are measuring two different things they can't be directly compared, but a rough comparison is possible. Lumens x 80 = the approximate light output in millicandelas. A 15 watt fluorescent light has an output of 870 lumens or roughly 70,000 millicandelas or 70 candelas. Individual white LED's have a light output of 2,000 to 10,000 mcd's. Caution: Super Bright Leds can be intense enough to injure the human eye at close range.
