How many lumens per square foot retail store?

First follow LiteHome to learn more about light Candela & Lumen (Cd & Lm) The unit of light intensity is candela, which is based on the intensity of ordinary candle light, but is now defined as 1/60 of the light emitted by a black body radiation of 1 square centimeter at the solidification temperature of platinum. A light source is uniform in all directions. Emitting 1 candela of light means emitting 12.3 lumens, that is, emitting 1 lumen per unit solid angle. Lumen is the unit of luminous flow. Illumination (Lux) The amount of light spread on an acting surface is called illuminance. Expressed in lumens per unit area. One lumen per square foot is the amount of lighting placed one foot away from the surface of action with one candela. Sunlight from a clear sky during the day is about 1,000 lumens per square foot. On a well-lit dining table, it is about 20 lumens per square foot. The corresponding metric unit is lux, which is 1 lumen per square meter. 1 lumen per square foot is equal to 10.76 lux or close to 10 lux. In the United States, footcandles are used instead of US lumens per square metre, while the UK uses the latter to be identical. Lux is used in European countries. Reflection coefficient When light falls on a surface, it is reflected according to the properties of the surface. This property is called surface reflectance. The reflectance of a white surface is close to 100%, while the reflectance of an asphalt road is only 10%. The brightness of

New improved version of IP66 tube light

We have the tube waterproof luminaire in a new improved version with higher power, more efficiency and improved light quality. The Tubular waterproof lights are flexible damp proof luminaires for many versatile applications, with versions offering luminous fluxes of 2000lm and even 15000lm for installations with very high ceilings. The Led Tube Light comes in 5 lengths of 0.6m, 1.2m, 1.5m, 1.8m and 2.4 metres while offering excellent luminous efficacy and energy efficiency of 150 lm/W in a robust (IK08) and water-resistant (IP66) polycarbonate housing. There is no electrostatic discharge risk since the LED module is integrated into the cover. Suspension and anti-theft kits are included. The new version has a flicker rate of below 10% and a colour consistency at 4 SDCM. There is also a greater range of light colours to choose from, with 3000K 4000K 5000K and 6500K. The Tubular waterproof lights are also available as single-battery emergency luminaires with automatic testing. A stand-out feature of the Ip66 Tube Light is its simple and easy installation thanks to without mounting clips and tool-free wiring. The luminaire comes pre-wired and features a tool-free electrical connection, with a large adjustment range for the reuse of previous mounting holes. The easy installation of the luminaires opens them up to a wide range of exciting applications. They can provide ideal vertical illum
