I recently discovered the wonders of 5050 led's but I don't know much about them. Couple questions:

1: About how many lumens do they output each? I have read some places say 20 lumens but that sounds wrong.

2: How reliable are they?

3: Is a single color white 5050 much brighter than a single RGB 5050 set to white?

4: How much power does a 1 meter strip with 30 leds require?

Any other info you want to throw in about 5050's is much appreciated.

Thanks in advance!
