I use it for office lighting, very convenient as it is adjustable and its clamp easily attaches to the table or shelf. I did not expect such good construction with so little money

Very user-friendly and with plenty of options in terms of lighting intensity. The best choice for a low budget.

Very nice light fixture that really surprised me with its quality and brightness! I didn't expect such an affordable device to have such good construction...
Its "base" is the clamp as shown in the photo. It has 3 different lighting modes and in each mode you can control the intensity...! The phone holder seems very good and so far I haven't had any tragic incidents.. It is "tight" to the point where you need to apply some force to place the phone.. The "cables" are also quite flexible, without meaning that they can't withstand the weight of a phone or are fragile.
The only thing one should consider is the power supply, since it is USB. It does not include an adapter, which means you will have to sacrifice one or connect it directly to one of your computer's ports, if you choose to place it near it.. However, the computer must be on in order for the light to receive power.
