SUMMARY: Aside from possibly destroying your phone, this is a 5-star product, with a few minor criticisms.
WARNING: The power supply uses a USB C tip, just like most phones, tablets, and some laptops. If you accidentally plug it into your phone, it'll likely be instantly destroyed: the light's adapter outputs 20V, but most phones can only tolerate 12V at most (with 9V and 5V also being common). VeriLux should really implement USB PD to prevent this, or at least use a red tip and/or attach a warning label to the end of the cord. (I recommend you attach a label yourself to prevent very expensive mistakes!) There's no warning about this in the manual or anywhere else as far as I can see. (I don't have a USB C breakout to verify this; perhaps someone else can test and see if there's a safety mechanism, although my conversation with VeriLux about this implied there wasn't.)
POWER CABLE/STAND: The power cable is difficult to plug in with the stand attached to the back of the unit. You might have to store the stand separately if you're wall- or arm-mounting this.
TIMER: The timer isn't intuitive, but there are well-written instructions.
BRIGHTNESS: VeriLux tells me they guarantee the rated lux at a distance of 6" for all of their lamps. That said, this model is much brighter than my VeriLux HappyLight VT15, which is also rated for 10,000lux. There are four brightness settings, which I'd guess are each very roughly double the brightness of the previous.
DISTANCE/TIME: If your eyes are more than 6" away from the lamp, you might need to use it longer to get the same effect as the recommended 30mins. From the inverse square law, at 12", you need 4x as long (2h), while at 18" you would need 9x as long (4.5h). This is probably true of every therapeutic lamp.
COLOUR/WARMTH ADJUSTMENT: The coolest setting is like daylight; this is likely to be the most effective for SAD/depression. The warmest setting is closer to indoor, evening light in most homes, but it's definitely not free of blue light (if that matters to you).
I use mine with a tablet arm (B07PT3T8TV) which will *just* hold the tablet. This makes it easy to mount the lamp over my computer's screen. As a bonus, at a low setting, this helps illuminate me for video calls.
