Reef bundle (spectrum suitable for corals)

Ideal spectra are especially desired in marine water aquariums due to the demands of corals. This bundle (controller board and LEDs) was designed to offer a very wide blue spectrum along with a high UV ratio to stimulate the fluorescing effect in corals. The optimum illuminable area per bundle is around 60cm * 60cm.


Using this simulation you can also try different other LED configurations. Your goal would be to minimize gaps. Please note that in practice there will be minor deviations due to component tolerances. As a default (when refreshing this page) the reef bundle configuration and recommended dimming is loaded.

LED types, counts and dimming:

pc(s) LED warm white 10W (~3000K)

pc(s) LED pure white 10W (~6000K)

pc(s) LED cold white 10W (~20000K)

pc(s) LED royal blue 10W (~445nm)

pc(s) LED blue 10W (~470nm)

pc(s) LED CVU 20W
Cyan (~490nm)
Violet (~420nm)
UV (~380nm & 400nm)

pc(s) LED RGB 20W
Deep red (~660nm & 730nm)
Green (~520nm)
Blue (~470nm)

This configuration needs 1pc CoolTWILED and pc(s) CoolTWILED SLAVEPLUS.
Resulting power: ~W.
