Clamp Desk Lamp, Clip on Reading Light, 3000-6500K Adjustable Color Temperature, 6 Illumination Modes, 10 Led Beads, AC Adapter and USB Cord Included (Black)

I needed a little reading light I could clip onto my laptop desk. This works great. Clip is strong and holds on tight. Light has 2 brightnesses and 3 colors so a nice choice there. Bendable arm is flexible but also holds in whatever position you put it in. One note: It needs a USB port so if you don't have that you'll need an AC adaptor for it. I plug it into my laptop so it works great for me as-is.

Lo pegamos con el clip a la cabecera, se ajusta a varios grosores. Tiene botoncito para luz blanca o luz amarilla. Ilumina super bien y la varita y flexible, la puedes mover para donde tú quieras. Super útil!

Excellent product!

I bought several of these for an art booth. I didn't realize it's a USB plug only. I had to buy adaptors. Nice lights, good flexible arm, I like the 2 power levels and 3 light temperatures. They're not super bright but are fine for a desk or tabletop.

This works over a tiny fish tank (2.5 gallon / nano sized) with live low/medium light plants. I love that it has a USB plug - so I can use rechargeable power-banks (like you use for your phone - how long it lasts in next paragraph). Outlets are scarce in my home. This round light would be better over a bowl -with a round shape - since it throws light in a circular shape. My tank is rectangular and the light hits a circular area more strongly than the rectangular edges, I should have sought a rectangular shaped light.There are 3 color settings, very cool, neutral, and warm; plus high and low on each color setting. High on Neutral offers the very most light according to my phones light meter app. On that setting, it ran for 8 to 10 hours on my 6,000 mah battery. (Lost track after 8 hours - I think it is closer to 10.) On the low setting of warm color - which seems to be the least light - it was running for 8 hours when I turned off my 3,000 mah battery (would go longer). Too early to report on success for growing - will report back - but three tiny cryptocoryne plants are perkier since using it for only 2 days.The clip is functional, but they included a flat item with a hole that supposedly can be connected to the clip. It doesn't allow the lamp to stand free and it doesn't seem to make a good buffer when clamping. To me the flat item seems un-necessary.The goose-neck is good and bendy with sufficient strength to hold. Personally, I could have used a longer neck, but this should be good for most folks.There's a plug that can be used between the USB plug and wall outlet if you choose not to power by battery. I don't use it. Over all, I really like it. Some folks complain it doesn't produce enough light. Not sure if they're trying to light a room with it, but when the only thing turned on in my room is the fish tank light (this light) I have plenty of ambient light in the room for relaxing. (Light is about 5' away from me). It's far brighter than a nightlight for certain. It feels like it might be about as bright as a 40-50 watt incandescent for lumens - but I haven't checked. It is not as bright as my 60-watt incandescents.Hope this helps someone.
