0.3 W/m² Limit

The 0.3 W/m² limit is the maximum erythemally weighted UV output allowed for sunbeds sold and used in the UK and the EU. It comes from the product standard for UV appliances (BS EN 60335-2-27) and applies to every bed in a professional studio; a bed built to it is often called a UV-Type 3 unit. It is a legal ceiling on what the equipment gives out, not a measure of how dark you will go or how long a session should be. At MEGATAN Studio, session lengths are set by our team at your consultation.
