LED controllers for fish tank lighting (fresh and sea water) and LEDs are in stock and available immediately. Nonetheless, please plan your demands in good time.

CoolTWILED 3.x is a wireless programmable 12channel LED controller/driver board. Configuration is possible via browser on almost any platform: Windows, Linux, Android, Apple IOS.

New: 20 Watt CVU LEDs combine cyan (490nm), violet (420nm) and UV (380nm & 400nm).

On request, CoolTWILED 3.x SLAVE is available with fan ports (so that two additional fans can be connected per board).


Please order via email

If you have questions, please read the pages below “Available for ordering”.

Please order via email: mail@webtemp.org

CoolTWILED 3.x SLAVE

This is an extension board (no standalone operation) for CoolTWILED 3.x and BlueTWILED 2.x.

You can connect one or more of these to increase the number of outputs, so there will be multiple outputs “A”, multiple outputs “B”, and so on. Outputs having the same letter behave alike, so it makes sense to connect the same LED colors to the same ports (i.e. White to “A”, Red to “G”, and so on).

For this reason and also to prevent confusion the master and all slave board should have the same current configuration.

The connection is made through the cable of CoolTWITemp 1.x (temperature sensor) (please do not forget to order one).

The technical data of the slave board matches those of the master board, so currents from 300 mA up to 1500 mA are possible per output (A-L).

Ordering and prices

There are four bundles available which already include LEDs:

  • DIY kit CoolTWILED 3.x SLAVE “6+2”: 119 EUR plus shipping

6pcs pure/cold white or royal blue LEDs (10W each) and 2pcs RGB (20W each)

  • DIY kit CoolTWILED 3.x SLAVE “12+4”: 159 EUR plus shipping

12pcs pure/cold white or royal blue LEDs (10W each) and 4pcs RGB (20W each)

  • DIY kit CoolTWILED 3.x SLAVE “24”: 159 EUR plus shipping

24pcs pure/cold white or royal blue LEDs (10W each)

Please tell us how many LEDs of which color (pure/cold white or royal blue) you need.


Please also take a look at the Reef bundle (spectrum suitable for corals).

For all bundles we will configure and test each LED port current accordingly.


Optionally, all the Slave boards are also available with two fan ports for additional cooling fans. These will behave exactly like the ones connected to the Master board:

  • Surcharge SLAVEPLUS (fan ports): 10 EUR

CoolTWILED SLAVE is also available without LEDs:

  • DIY kit CoolTWILED 3.x SLAVE: 79 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

Assembly

The board is pre-assembled with SMD parts and is shipped along with all needed THT components.

Please solder carefully, temperature controlled and using a “no clean” solder wire. Please do not clean the solder joints. Keep the static shielding bag. Avoid static discharge and swarf (for example during and after metal works on your lamp).

Pay attention to the polarity of the components.

Some detailed notes on soldering can also be found in the Frequently asked questions. If there still are questions, difficulties or doubt, please send an email: mail@webtemp.org.

There are 4 mounting holes on the board. Please use appropriate screws and spacers to avoid short circuits. A mounting kit can be ordered separately. Mount CoolTWILED directly onto the aluminium plate that also carries the LEDs. This will keep the cables short and ensures proper cooling.
