SOX(-E) - BY22d Gas Discharge Lamps
A SOX Gas discharge lamp or low pressure sodium bulb is a tubular vacuum lamp. They are designed for emergency lighting in places like highways. The lengths of the light bulb vary from 30cm to 112cm. The BY22D base is a Bajonet base with a diameter of 22mm. Gas discharge lamps become very hot, therefore making it important to let the light bulbs cool first when replacing. Never touch the light bulb with your bare hands but use a tissue, the grease on your fingers can shorten the lifespan of the light bulb.
