Apologies.....I'm sure the answers are out there.......

Hi everybody, hope you all well. I posted approx 4 years ago that I had managed to buy a LL colour changing lamp, that worked with a heating element and LEDs.......well, I've had 3.5 years of joy with it,managed to get it working with some carefully placed tin foil, but now most of the LEDs have stopped working, only the red ones work........looks ok......but I'm thinking of tinkering.......

Today I've run it on a standard LL base, for approx 6 hours, and all I'm getting is one large lump hovering in the middle......sometimes it goes up slightly, sometimes it goes down slightly.......but generally it sits there

Any ideas on how to turn the large lump into many smaller lumps? Is it possible? I am thinking of adding some colour to the liquid, so that I have a white wax / green liquid lamp

Thanks all

James
