The image provided is for illustration purposes only and the product that you will receive may be an updated design that does not look exactly the same.So, not octagonal but rectangular and of different dimensions. Not using an amber glass filter but amber LEDs instead. On their website they list the wavelength as 590-595nm and that might well be useful for "Yellow LED therapy" which uses this amber colour. But the company has outdated pictures, wrong dimensions, and often give wrong wavelengths for their products. You can't rely on any information provided by the company, they are obviously guessing what their chinese supplier might send them. There are no indications of stock available. If you buy a quantity bigger than the available stock, when new stock comes in it might be entirely different. The product however IS GREAT, thus 5 stars.
