Great transportable phototherapy device. 54W = good power. 630nm, 660nm and 850nm wavelengths.
Considering the design, the form makes this a very transportable device. It even comes with a drawstring bag to store it. With a rating of 54W, this has ample power, similar to some of the more powerful bulb types. It covers 630nm, 660nm and 850nm wavelengths, as opposed to most bulb types that don't only include red light 660nm and infrared 850nm.  I also feel the rectangular format issues a more uniform exposure.<br />The power cord has the power button, which also accesses the timing function. Successive taps of the power button will cycle the timer settings.  Including the usb power plug is a smart decision, making the item a complete product. Now, the user won't have to search for an available usb port, or a spare usb power plug. The only disappointment is the lack of a user guide/manual. But, to be fair, other red light therapy bulbs that we have did not have a user guide/manual included.<br />Another included accessory is the folding stand. It can unfold in various configurations to allow numerous positions for the lamp. See the attached photos, I show two possible configurations, with the lamp in horizontal and vertical orientation.<br />Attached are photos to show real world images of the product, with a ruler for size reference. Note the compact size, and the smart design. There is no fan, operating in complete silence. This product could easily travel inside a gym bag or luggage.<br />If you are searching for a credible, quiet photobiomodulation (red light therapy/phototherapy) lamp for skin, muscle treatment, this deserves serious consideration. It matches the descriptions and images in the product details, and appears to be a very well crafted device. It earns a solid 4.75 star rating, with a high level recommendation.
