12v vs 240v lamps

Same for the master / slave jobbies (varilight IIRC) that TLC do.

"Brighter" could mean many things (gives off more light, illuminates the target object better, illuminates the room better, has a higher intensity beam centre, etc). You weren't specific.

A 12V filament lamp of that power is significantly more efficient than a 240V filament of that power. If you want to design the most efficient filament to operate at 100W, it turns out to be one designed to run on about 55V. (It's not going to be very different for 50W.) 12V is nearer to this peak efficiency than

240V. That's also the reason a US 100W 120V lamp gives off more light than a UK 100W 240V lamp.

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember "Trevor Smith" saying something like:

The packets didn't mention Xenon filling by any chance?
