Ive got a question about lights. A few years ago when I got my last light everything was halogen. Most lights were 10-30 watts, anything in the 20+ watt neighborhood was pretty bright. Now I am looking at some lights online and most of them are LEDs, and they go by lumens or lux instead of watts.
Can anyone tell me how these compare? For example, a 20 watt halogen is comparible to 'x' lumens in a led.
Also the halogens had a tendency to be not very white. Sort of a yellowish light, are the leds like this or are they a white light?
And lastly, I keep seeing lights that have a 'usb' option. Does this mean you can actually charge the light by plugging it into your computer? This idea was like pink flying elephants last time I was light shopping....
