Chihiros Series A plus LED lamps are specially created for densly planted, open fresh water aquariums. They have a very slim design and the evenly distributed LEDs illuminate every tank completely. The LED cover is made of aluminum alloy and finished with anodize surface treatment, which effectively reduces the heat generation problem of the high luminosity LED lamps and prevents the lamp from rust. Other than the Series A lamps, these lamps have nearly the double amount of LEDs built on, which amounts in a recognizable rise in the lumen per litre ratio. This makes these lamps ideal for deep and densly planted tanks.
It comes with a manual dimmer (not with 901 plus and 1201 plus), which allows an easy adjustment of light intensity in 7 steps. The different dimming steps are 100% - 90% - 80% - 70% - 60% - 50% - 30% of the light output. This comes in especially handy while starting an aquarium, where the light intensity should be raised slowly and according to the plant growth. When used together with a time switch, the last appointed setup of the dimmer is preserved.
