This 36 inch screen is exactly the same LED device that I used at a spa in Westchester NY. So I opted to fit my home with a personal 600 to use daily for maximum benefit..the device provides option for 2 wavelengths, as I understand. Thus, you may choose your treatment on the touchscreen, time exposure, and alter it at will. The dual treayment lights emit a warm red and yellow light, alternating, it appears. It is exactly the same, solid construction, securely mounted device I was hoping to receive. Provided is a suspension hook and supports with addl connecting cables for use with multiple screens, an option I'm considering. It also has silicone support legs so that it rests quietly against the door. For now, the 600 provides maximum light and coverage area, when seated on a stool or standing. In 60 seconds it was operational from the box, suspended from the robe hook on an 18th century solid door. I provide guests with option to use it as part of a spa experience, as well. Could not be more pleased with the design, operation and value of the Platinum 600!
