Yes. The lamps are compact fluorescent bulbs. The color temperature is very close to daylight (5500K). The lampholders sit on a flat surface but have several variable joints (swivels) to achieve about any desired angles. The rig is for table-top product photography and does not involve flash. I wish I had a third lampholder for overhead illumination which I believe would completely eliminate unwanted shadows.

It is not battery powered. It is plugged in. I bought around Christmas and I have had no problems with it.

It needs to be plugged in to a usb socket to be powered. No on/off switch thus nothing is charged.

Powered by USB, whether off laptop, desktop, or direct plug with a USB port. I love it!

This is not powered by battery. It is powered by plugging it into an electrical outlet.

It can be powered from a wall outlet. The plug folds into the back of the charger.

It is recharged from a regular household outlet. I hope that answers your question; I am not a good enough electrician to give you any other answer.

Completely powered via USB. Has a double USB cable to plug into two USB ports should your computer not supply enough power. Works like a champ.

It's powered by the USB cable it comes with. I'm happy with this hard drive. It has an extra usb power cable if main usb output is not giving it enough power

It is powered via the USB connection from your computer(s). It has worked great for my husband and I sharing two printers between our two computers.

It is powered by an internal battery. It is charged by a charger that comes with it. The charger plugs into a wall outlet, it is not a usb charger.

This was a gift for my son, and he said it works without being plugged in, with being plugged into an outlet, and it works being plugged into a computer. I hope this helps.

you plug it into a wall outlet and then into the computer with a usb cable. so the power does not come from the computer
