Comparing Optronics LED Lights Candela Output


I am trying to decide on some interior LED lights for my 7x14 enclosed trailer. I have the BUL78CB installed below my brake lights, as a backup light, and they work great. Review posted 10/29/2012, However, I was considering the ILL31CB light for the interior after reading a review with some interior pictures. The brightness ratings of these two lights are listed in different units, so its hard to compare them. What would the lumen rating be for the BUL78CB? ILL31CB: 70 Raw Lumens / 53 Effective Lumens BUL78CB: 125 Candela No lumens listed I also went to the Optronics web site, but they didnt have anything listed differently. Thanks.

My contact at Optronics was able to give me a brightness comparison between their LED lights # BUL78CB and # ILL31CB. Although both use 10 LEDs, the BUL78CB uses super diodes that deliver a lot more actual light output.

Optronics was able to give me the candela specification for each light. This scale differs from lumens but it still gives you a good comparison basis. A common candle emits light with a luminous intensity of roughly one candela. Light # ILL31CB offers 44 candela output while light # BUL78CB outputs 125 candela.
