reasonably well-constructed overall and it's noticeably more compact and slimmer than many others with similar style and design that I've come across (several dozens). It's fairly bright although it's far from the brightest that I've come across. It comes with the usual clip and attachments as well as some color filters (which would've been nice a few years ago) but the truth is many others have built-in RGBWW LEDs instead which makes these filters seem, well, rather outdated.

≡ Brightness
It has 5 levels of brightness (for each color temp) which is considered low because many others have 10 levels to choose from. It claims to have 250 lux @ 50cm and based on some quick tests it's around 214 lx @ 50 cm so it's, well, not too bad. Also, its light is more diffused in comparison to many others so perhaps that play a role in the reduction of brightness.

In either case, it's reasonably bright and it should be sufficient for close-up photography and/or video chat etc. I don't think this will be useful for most people at a distance greater than 50-60cm (~ 2 ft) because it's simply not that bright. Of course, it really depends on individual use case which could vary quite a bit so I'll just leave it at that.

≡ Color temp (modes)
It has the typical 3 color temps along with a memory function that remembers the color temp as well as its associate brightness level which is nice. Many others will reset either the brightness or the color temp to the middle (or some other arbitrary level) which is just annoying.

It also claims to have a color temp of 3000-10000K which appears to be false although I haven't the means to actually measure it but it simply does NOT look like it's 10000K to me in comparison to others that are 6000-7000K (and this one at best looks like very much around that range as well).

Btw, this is one of the very few that actually use a slide button to turn it on/off which I do appreciate and find it much easier to use than the hold-for-2-second to turn it on which is very annoying to me personally. However (there is always one, isn't it?), the design of ALL of these buttons are poor because they reside in recessed slot (pic 7) that may look nice and streamlined but it's actually more difficult to use, at least for me.

≡ Clip
It comes with 3 different attachments and all of 'em are fairly well-constructed and work as expected without issues although all of' of 'em are quite common nowadays and they're often included with these phone light/panel. The adjustable clip in particular works fairly well and perhaps a bit better than most others because it can tilt slightly more than 180° that most others cannot which I DO find rather useful in many situations.

A side from that, it does have a common and typical design found on nearly all other phone/selfie light of similar design and style. It's easy to work with and it's reasonably tight without being overly so. Likewise, the cold show adapter and the 1/4" screw adapter work just fine as well.

≡ Value
All things considered, this is a fairly decent LED light for video chat or close-up photography (or whatever else you wanna use it for) that's reasonably well-built with decent brightness and comes with 3 attachments along with 3 color filters that work reasonably well given the circumstance. It's somewhat reasonably priced at $34 for what it provides and its overall build quality, usability, features, and performance. However, you can get a similar light capable of RGB for roughly the same amount of dough if you care to shop around. Your mileage might vary.
