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.
The colour code is a combination of colour rendering (CRI) and light colour (Kelvin). The first number indicates the colour rendering (1 = very poor colour rendering, 9 = maximum colour fastness). The second and third number contains the light colour. Example: the colour code 830 consists of good colour rendering (8) and warm white light (3000K).
Every bulb or fixture has an energy efficiency class A to G. Energy label A is the most efficient and G the least. LED lighting is the most sustainable lighting technique. Even if a LED bulb is rated E or lower, they still save 70% of energy compared to conventional lighting with the same energy label. Why is it the same label then? To motivate LED brands to get even more durable.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.
