Grassy LeDio LED spotlights may be made in Japan but that doesn’t stop us from being able to use the Edison incandescent base in our own sockets. In fact, our Japanese contributor Taka Kamata is expecting to receive these lamps in a few flavors today, including the brand new 21 watt all blue lamp, and we thought we’d go ahead and introduce these beauties in anticipation of his hands on product review. Much like the PAR 38 lamp from Nano Customs, the Grassy LeDio lamps feature a broad finned heatsink to contain the high power LEDs that grace the projecting surface. The edison base LED spotlights are available in different configurations of blue, white, and red LEDs that are arranged to produce 5 color temperatures shown above. 
The 7, 13 and 21 watt lamps run roughly about $10 per watt which is a reasonable price for long lasting light sources and high quality Japanese construction. We have extensive experience using all blue LED spotlights to an almost overwhelming effect and even with broad directivity we still noticed too much unusual color shifting in a range of corals. The balanced color flavors are likely to produce much better color rendition and more realistic color from an LED light in aquarium and reef corals. The 60 degree directivity of these lamps should be able to cover a 30cm by 30cm spread, or you know that you’ll get decent light spread for about a square foot of your nano reef. We look forward to seeing Taka’s first impression with the Grassy LeDio LED spotlights and we’ll be sure and put them head to head with the EvilC66 PAR 38 lamp from Nano Customs when we get the chance.
