The bulb (with aluminium heatsink) is 11×40×23 cm overall and 200W (1165cd/cm²), with monitoring and sync options.
Bcs it's a neat design:
But perhaps to note - bulbs like that are only if you want to keep those giant rotating fresnel lenses (and even with that those LEDs on that bulb still need a lens on their own).
The simpler solution is to use one of the new designs, without the old lenses or even without the whole old lighthouse structure, eg:
That's really cool, thank you.
I like how it goes from being a light turbine to a water-cooler.
Lighthouse are cool, i'd be really sad to see the structure go.
