Cheap Wish LED lights

[Gnox]

I've just gotten 3 very cheap Chinese LED clip on lights for my 120l tank. They are ultra bright, but all white LED.
I'm toying with using something like nail varnish to paint a few individual bulbs red and blue to soften the light and help plant growth.
Has anyone tried anything like this before - or am I wasting my time even trying?

You could put some coloured plastic in front of the lights. I’ve used sweet wrappers (you can have blackwater with the brown ones ).

Actually, it is quite easy to snip out an led and solder in a new one. No high voltages involved. ..Just need a steady hand and a fine pointed soldering iron.

Depends on the type of lighting. On these it wouldn't be that simple! They are smaller chips, which require a reflow oven to do properly. You risk burning other LEDs or damaging the board trying to do it with an iron

Best excuse to buy a box of Quality Street!

Went with blue and red nail varnish over the outer plastic cover. Working brilliantly - harsh white tone is gone and reduction in green spot algea

I second the Quality Street option!
Been using the red wrappers to cover my rifle night-light LEDs for years, but you will have to force down all the sweets...
