CoolTWILED is a wireless programmable LED controller/driver board particularly designed for fish tank illumination (fresh and sea water). Configuration is possible via browser on almost any platform: Windows, Linux, Android, Apple IOS. It provides high efficiency LED drivers on each of its 12 channels so that high-power LEDs can be directly connected. Currents from 300 mA up to 1500 mA are possible per output (A-L).

We recommend purchasing the Reef bundle (spectrum suitable for corals) or the Fresh water bundle (full spectrum).

CoolTWILED is also available without LEDs:

• DIY kit CoolTWILED 3.x: 134 EUR plus shipping

Here you need to tell us the needed currents for every LED port in this notation (example):

A: 1000 mA
B: 1000 mA
C: 1000 mA
D: 1000 mA
E: 1000 mA
F: 1000 mA
G: 700 mA
H: 700 mA
I: 700 mA
J: 700 mA
K: 700 mA
L: 700 mA

Either contact us via email mail@webtemp.org or just use one of the options shown below. These bundles are ready for shipment. Please make sure your shipping address is correct.

LED configuration of the bundle. The prices given here also include a 20x4 display and the shipping costs:

• sun rise/set can be simulated by exact time or based on calculated elevation for given coordinates anywhere on earth
• brightness values for each channel can be programmed for any point in time or any sun elevation
• intermediate values are automatically calculated in real time
• moon phase simulation
• random cloud and thunderstorm (incl. lightning) simulation
• dimensions 100 mm by 100 mm (4“ by 4”), height approx. 25 mm (1“)
• LCD display (16×2 characters) and approx. 25 cm (10”) cable
• WLAN module (b/g/n 2,4 GHz) for programming and upgrading the firmware (please see the screenshots)
• IR receiver for easy access to main functions via any universal remote control (not included; must support RC-5 standard)
• on-board temperature sensor (emergency shutdown on excess temperature)
• real time clock (which continues to run without power supply; optional coin cell CR2032 not included due to shipping regulations)
• 24 V DC input (12 up to 30 V are possible)
• 12 highly efficient LED drivers (currents from 300 to 1500 mA can be configured)
• each of the 12 LED ports can be dimmed separately (= 12 channels) in steps of 1/4096
• higher light demands can be satisfied by using one or more additional slave boards
• two ports for 3pin fans (max. 1 A)
• the fans can either be operated depending on the LED brightness (power) or temperature (CoolTWITemp 1.x (temperature sensor) necessary)
