We’ve already looked all up inside Kessil’s A150w LED spotlight and it’s matrix array LED chip but the ultimate proof is in the pudding. Pictured above is a sneak peek at Ecoreef Two which has been growing medium light corals with the Mame 49 watt RGBY LED with great results especially in the color rendition department. During Kessil’s visit earlier this month we had a chance to compare Mame Design’s pricey hot rod LED light against all three of the A150w spotlight colors.
The Kessil 10K spot is the most balanced in color rendition with the brightest appearance while the 15K adds that extra bump of blue that some reefers are looking for. The 20K color is really a full blown actinic blue light which doesn’t show as well in photographs as in real life, but it could make for a great supplemental light to white light sources. The other feature that isn’t outwardly apparent in the images is the spread of the A150w spotlight which was much tighter with its reflector and lens than the Ecolight’s completely unfocused RGB LEDs.
In some ways we like the way that the Mame Ecolight really fills the tank with light, even in between the corals but there’s also a dramatic LED spotlight effect when more narrow optics are used as in the A150w. This is not a comparison of the overall performance of the ~$1500 Mame Ecolight and the $260 Kessil A150w, just the different color renditions. We are big fans of both lights but since the Kessil LED lights are made by an American company, hopefully we’ll be seeing a whole lot more of those. Bay Area resident reefers ought to mark their calendars for BayMAC 2011 happening May 14th because Kessil will be there to show off their fancy spotlights.
