Hope you do not mind me contributing to your thread Marmar! Took delivery of the Hipargero 100 watt led lights a few hours ago. Walking through the setup was very easy after having read the instructions. The Master/Slave equipment setup was easy enough as well setting only the Master designated unit (time/and coral type). No problems mounting the lights on 10mm glass rimless tank. The picture does not do justice to the amount of illumination provided by the led lights. The Bozily/Relassy (1-2 watt leds) were rated at 300 watts and these Hipargero (5 watts) are rated at 130 watts each. Without a Par meter I can only offer the Hipargero are extremely more powerful at depth. I like the shimmering effect of the lights on the sandy bottom something hardly noticeable with the Bozily/Relassy.
In the past I owned the Maxspect Razor 300 watt Led reef lights and loved them. At this time if "reliability" does not come into factor these Hipargero provide the same illumination for a fraction of the price.
