Made a LED light,... Old news ? [updated]

Hi,

I'm new to this forum.
I have just made two LED lights for my small freshwater tanks.

I'm guessing it is old news, but if anyone is interested, I can make detailed post ?

Attached are a few quick pictures with my phone.

(the lights are designed so that they can be mechanically mounted in the T8 fixtures)

Ok, here are some pictures.

- The lamp is made from single piece of aluminium heat sink.

- The wooden ends are 25mm and fits in the T8 fixtures of the tank lid.

- The LEDs are 10W 10K each, run at 700mA (7.5W)

- The acrylic serves as a splash guard, and ensures airflow along the profile.

- It currently runs at 43C

Thanks,

Yes I'm experimenting with the RGB LEDs for night light.
So far I have learned they do not handle splashing very well !

What heatsink is that? Is it made for LEDs, or normally used for something else? Looks ideal for what you are using it for.

Hi,

It is a general purpose heat sink I found here:

It is 1m long, so you could replace larger flouresent tubes.
