Because of the size of the hall of warriors, cinematographer Jonathan West used bleached muslin to hide florescent lamps in the window treatments.

It's a lot of work, expense and risk and there's also the environmental consideration that most HID lamps contain high levels of mercury, which makes recycling a headache.

Fluorescent lighting, CFL lamps, mercury and sodium discharge lamps and HID lamps are all gas-filled tubes used for lighting.

High-intensity discharge lamps (or HID lamps) are now common where a very bright light output is required, for example in large follow spots, HMI (hydrargyrum medium-arc iodide) floods, and modern automated fixtures.

The S-L variant also has a 17" 7-spoke alloy wheels, 3-spoke leather steering wheel, HID lamps, and has blue leather seats.

For HID lamps there is no improvement of the lamp efficacy in using higher frequency, but for these lamps the ballast losses are lower at higher frequencies and also the light depreciation is lower, meaning the lamp produces more light over its entire lifespan.

Many HID lamps are designed so as to quickly extinguish if their outer UV-shielding glass envelope is broken.
