What to say about this fantastic masterpiece, the most powerful consumer blacklight on the market. It comes in a sturdy metal casing (+ 2 small bases for wall or table) with 18 ultra-powerful 3w UV LEDs that can illuminate a large space with a 120-degree beam angle (due to the parabolic mirrors behind the LEDs), enough to evenly distribute light throughout the area. However, something very important, modern blacklight UV LEDs have a wavelength of 395~405nM (UV-A), which is different from what we know from the 90s (UV-B, around 365nM wavelength). The difference is that UV-A displays a significant purple color in the space (mainly near the light source), which is negative for some because it doesn't create that dark feeling in the room, but as a positive, it covers a larger distance and is more intense, able to illuminate objects that are several meters away. On the other hand, UV-B does not emit the purple color, keeping the space black and darker, but it has less power and can only illuminate objects that are at a close distance. If we are talking about a large space where we want intense glow-in-the-dark elements, then this is the way to go, as traditional 365nM UV tubes will not strongly cover the area. This specific bar also comes in smaller sizes with fewer LEDs, depending on your space, choose the appropriate one. This is quite large and certainly not just for a small room or living room. However, I don't think there are UV-B LED lamps or bars available on the market, so for such a phase, this is a unique choice. Also, note that it does not have any program or programmability, it is simply ON and OFF. Finally, I would like to mention that Beamz is a very high-quality and well-known company for household, semi-professional, and professional (up to a certain point) lighting.
