HappyLight Halo - Cordless, Rechargeable LED Light Therapy Lamp with 360° Magnetic Base and Adjustable Brightness and Color, 10,000 LUX UV-Free Full Spectrum Light

The good: This is probably the only rechargeable SAD light on the market. It offers three different light temperatures and four brightness levels and has a timer that you can set between 10 and 60 minutes in 10 minute steps. The light is flicker-free and a good size to sit on a desk or breakfast table. Its ingenious magnetic base allows for flexible position adjustment. Good quality all round.The bad: the rechargeable battery only allows one or two sessions at medium brightness so you have to recharge it every time or use it on mains power. Connecting the charger is fiddly - you have to take the lamp off the base to connect it and then re-align the base to the charger socket. The charger has a US plug and no European adapter is supplied (but it will work on European voltage). Its cord is just under 2m long. The control buttons are on the back and are all touch activated and flush with the case. You can’t feel them and can only see them if you turn the unit round, and it’s too easy to change the settings by mistake when doing so. The timer button is not intuitive to use.

It didn't work. It came without a UK plug. The American plug didn't fit. We obtained an American plug from elsewhere, but the light still doesn't work. It is law that items purchased must have the items with thew ability for the item to be used. Sending an American plug which can't be used here in not legal. Then there is the problem of sending it back, instead of it being collected and the money repaid.

The charger is non-standard (usb-c socket but wrong voltage), and replacements are not available in the UK. Also if you accidentally use their charger with your phone or laptop it can fry the device. Not sure it’s even legal/CE compliant.The lamp itself works well initially and looks good, but misplace your charger and it’s a £100 paperweight.

I was surprised how this helped my mood and energy last winter. I sat with it in front of me (about 18 inches) for about 30 minutes while I had breakfast and read. The brightness settings are a nice option, but changing them didn't affect the results of my day. It's easy to take with you if going somewhere for a few days. Excellent quality.

Very nice light. It works well. I like that I can carry it around with me during my busy morning

Product is superb. Arrived a day early, the magnetic base is convenient, and all the light preference settings/times are perfect. Too soon for real results but so far find it very pleasant regardless.

I choose this Happy light for the convenience of being able to move it around without a cord attached.It is a nice size that can fit just about anywhere. The angle of the light can also be adjusted in the base.It has been very helpful dealing with Seasonal depression. Its been a very rough winter here. I highly recommend any of the Verilux Happy Lights

I love the lamp and it has worked to improve my ability to stay awake and reduced my SAD symptoms. However the quality is poor for the price. The main issue I’ve had is the touch buttons for the brightness and timer. They don’t work well. The instructions for the timer are a bit odd and even after following them exactly it still doesn’t work or take the correct timer value. The battery also only can last about 40 mins which is ok, but I was expecting longer. I exchanged my first lamp for a replacement assuming it was a quality control issue, but the new lamp is exactly the same. Sometimes the brightness or color settings will just start cycling through on its own several minutes into the session. Very frustrating. Put real buttons on the next model.
