This is a very good LED light option, at a reasonable price too. Thank you for posting the data, which I incorporated in my lighting forum thread,
http://www.plantedtank.net/forums/sh...d.php?t=184368 This can be used for low light tanks up to about 28 inches tall, or medium light tanks up to about 20 inches tall. The 26 watt light should be significantly brighter.
