I am curious on doing a DIY LED light ring as seen in this video.

I appears that I know where to get all of the parts specified in the video. While I could not find a 10W LED strip, I have a 4.8W LED strip available for me, as seen in the link below.

I am not sure if its a warm light, but that's not the point I'm trying to make. I just want to get some clarifications out to better understand the LED strip specs given in the link. I will just paste them here for everybody's convenience.

1. Non-waterproof
2. Light Source: LED
3. Type: Flex LED Strips
4. Lamp Luminous Flux: 780-900 Lumens/Meter
5. Lamp Body Materials: Adhesive
6. Item Type: Light Strips
7. Input Voltage: Dc 12V – 3A
8. Working Temperature: -20 to 40 degree
9. Length: 5M per roll
10. Emitting Color: White
11. Lamp power: 12V 4.8 Watts
12. Working Lifetime(Hour): 50000
13. LED Quantity: 60 LED's/meter
14. Net Weight: 48g
15. Packaging size: 230mm x 65mm x 250mm (L x W x H)
16. Gross Weight: 308g

What I only care are numbers 7 and 11. From what I understand 12v 3A means that that is the entire power consumption per meter of the LED strip (or is it saying the entire 5 meters?) If I break the strip, since I am going to try make a Light ring for DSLR, does each LED has a voltage capacity of 12v? Given that the LEDs are presumed to be laid in parallel? Then in the Amps, should I divide the 3Amps to get each Amps per LED bulb?

on 11, does the 4.8W means that it is the entire brightness of the LED strip, or is it per LED?

Bonus, question: If you watched the video, the author used 6 AA batteries. I'm thinking of using two 9v batteries in series to get 18v and just step it down using resistors. Would that be safe?
