The alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque) that describes the color transparency.

Alpha LED flood lighting is a modular range of high output lighting with low power consumption. Commonly used in both high mast and indoor applications, Alpha lighting offers the latest in super-flood lighting technology for areas where 24/7 clarity of vision is critical to safety, security, and operations.

As a handy rule of thumb, a sitting room or bedroom will generally require around 10-20 lumens per square foot, while a bathroom or kitchen will need a stronger level of lighting, at around 70-80 lumens per square foot. To work out the lumens you need, simply multiply the square footage of the room by this figure.

A general guideline for bedroom lighting is a total light output of 1500-3000 lumens. You can achieve this by using a combination of different light sources, such as overhead fixtures, table lamps, and wall sconces.
