When 3reef first got a hold of Marineland's new Double Bright LED Aquarium Lamps a month ago, it was apparent that Marineland had done their homework for the aquarium hobbyist as they were built solid, yet light-weight, extremely easy to setup and move around for cleaning. Now we just received some more details that demonstrate that they are, in fact, very bright: 75 lumens to 1 watt! More details in post. Enjoy the pics. Marineland's Double Bright LED Lamps Marineland Double Bright LED Lighting System Highlights: The outer row on the Double Bright lamps are 1 watt white LEDs. The middle row are 60mW blue LEDs that really kick out the blue - note graphs below. Each lamp has a built in lunar cycle. The LEDs have a polycarbonate lens that enhance and protect the light and create a shimmer effect. A three-mode On/Off switch (daytime, lunar and off) and one power cord mean a lot less clutter. Note the slim-profile too. Flexible, easy-to-use mounting system will have this lamp on your tank in less than a minute. Initially there will be 3 sizes in the Double Bright LED series: The smallest will be for aquariums 18" - 24" long and has 6 one watt LEDs outputing 450 lumens. The middle model is for aquariums 24" - 36" long and has 8 one watt LEDs outputing 600 lumens. The longest lamp is for aquariums 36" - 48" long and has 16 one watt LEDs outputing 1200 lumens.

But lumens are a subjective rating based on what the human eye can see. We can't speculate too much on what these lamps will do with live corals without a PAR or LUX meter kicking out numbers and some real experience on reef aquariums. More on lumens: Par-lux-lumen That said, the 75 lumens to 1 watt ratio is a good one that does indicate there is some power behind these lamps. So with that and the light-weight, solid, low-profile construction - for now we will just have to drool a bit and wait until we can really put them to the test. PRICES NEXT WEEK. THEY WILL BE OUT BY THE END OF THE YEAR.
