Replacing a fluorescent tube with an LED tube creates many problems and doesn’t achieve ISO standards. Existing FL booths rely on the 360° light output from a FL tube. LEDs have a very narrow light distribution, creating light and dark ‘bands’ unless fixtures are optimized from the ground up.

LED replacement lamps are not controlled or calibrated, recreating the same issues as FL tubes, just using a different technology. No matching between tubes, batches, or locations. Not serviceable, not controlled over time, and expensive relamping is still required.
Patented JUST LED technology uses special reflectors, lenses and controls to exceeds the illumination quality of even our own
ISO-rated fluorescent fixtures. The results speak for themselves.
