Sodium-vapor lamp - Wikipedia ~ A sodium-vapor lamp is a gas-discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm.. Two varieties of such lamps exist: low pressure and high pressure.Low-pressure sodium lamps are highly efficient electrical light sources, but their yellow light restricts applications to outdoor lighting, such as street lamps, where they are widely used.

Light Emitting Diodes (LEDs) ~ High Intensity Discharge (HID) lamps that require a long time before restarting. • LEDs, being solid state components, are difficult to damage with external shock. Fluorescent and incandescent bulbs are easily broken if dropped on the ground. • LEDs can have a relatively long useful life. A Philips LUXEON k2 LED has a life time of about 50,000 hours, whereas Fluorescent tubes typically are .
