*****Tough all Laptop USB Portable LED lights are in same model and same size and almost same weight so it does not matters*****
1.) Mostly useful for the users who are not having backlit for their laptop keyboards. who works mostly in dark places or at night timings.
2.) Lighting is not much effective on your eyes, until you watch directly on led light.
3.) Works with All kind of Power banks, Mobiles, Tabs, Desktop, works with extension cable male to female also.
4.) Lighting range is very good till 20cm and gradually it looks lite till 2mts.( according to height it will change, check images for more)
5.) Tough it is very much useful in power cuts, but it does not give enough lightning in a room. If u think so, it is the one, no not at all..my opinion is.. better to go for emergency light where you can get for 250/-
