Hey guys, I was browsing this site and noticed that there are 180w LED streetlights available... they are obviously waterproof (good for our tanks) & include a 5 year warranty. Also at 80lumens/ W they are at least equivalent to a 150w halide etc. The downsides potentially... apparently 6800K colour temp. However, as with most white LED's this they tend to look closer to 10000k/ 12000k. Price....who knows what they cost(could be the earth)... however, if they are even 3 or so times more than an equivalent halide/ t5 system the long-term replacement costs should balance it out - 5 year warranty + 40000hour lifespan. http://www.electroniclights.co.za/en/pages_pro_item.asp?ID=783 Here are some pics: I also noticed another light which may have potential for nano systems = apparently use Cree Led's which are known to be good for marine systems. Downside...only 1 watt Cree Leds (20 watt in total)... & white & warm white colour temp - would actually have to see a pic of the light on & a spectral plot etc to know if it would be useful or not...but maybe it is a way forward for ppl looking to beat the electricity price & low availability of PL nano tubes in SA. http://www.electroniclights.co.za/en/pages_pro_item.asp?ID=820 some pics Well these are just some possibilities for us all to look into...they may or may not be feasible currently, however perhaps if they are feasible from a spec perspective, and enough reefers are interested they could all email the company expressing interest and asking for possible group discounts etc - let the company know there is a potential market out there for them to court.
