Earlier this week I received two LeDio 7 watt LED lamps and one Ledio 21 watt from my friend Eiji in Japan who is running the best community site for reefers, 1.023 World. Â Actually, he got some samples from Volx Japan who is making the Ledio series. The LeDio lamps I received are the 7 watt Mystery Purple lamp that has blue red and green LEDs in a 3:3:1 ratio,Â the 7 watt Aqua Blue has 3 white and 4 blue LEDs and the Coral blue that has 6 blue and one white LED. I measured PAR for each LEDs by setting up LEDs 6″ above the water surface for 20Gal long tank on a newly setup tank for LPS. Â As you know, the depth of the tank is only 12inch.Â PAR values for Ledio7 of both Mystery Purple and Aqua Blue are around 100 mmol which is an amazing value for 7 watts of LED. Â Then, you can easily image that Ledio21 has much higher PAR reading. Â Actually, the PAR value for Ledio21 is 679 mmol!!! Â This value is the same value ATI Powermodule (54W x 8 ) has over my 48inch SPS dominated tank.Â At these intense PAR values we can assume that we can maintain SPS with Ledio LEDs only. By the way, Ledio series designed for 100V, so I used a transformer to reduce the voltage from 120V to 100V. Follow the break for more images of the set up and the lamps side by side. I will be evaluating the popular LED spotlight form factor lamps over a range of corals and report back about my experiences with the Grassy LeDio lamps. So far, so good.
