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

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.

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

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

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.

Great light. Helps give me a good morning wake up when I wake before dawn. Really good therapeutic for early risers who have a hard time getting going and need to ramp up quick.
