These are available in warm white(similar to incandescent light) or cool white(similar to many fluorescent bulbs. I put four strips in each light fixture and am very happy with the light output. These also draw much less amperage from your battery so if you boondock, this will help extend your house battery life. Where did you find the 5 meter roll at?

You might consider soldering in a current limiting resistor into any LED circuit array you might construct.. Current limiting resistor calculator for Led's Is the online resistance calculator I most often utilize.
LED series/parallel array wizard Is very good at designing proper array.
Both of the above pages will design the circuit once you plug in the current values of LED's used.. diode forward current (mA) normally 15-25mA for 5050 type LED
If you have good specs from your supplier, you'll want to enter the typical forward voltage. Ideally you'll have something that looks like "3.4V @ 20 mA" which defines forward voltage and current at one point on the operating curve. If you don't have good specs, here's a table to help you make decent guesses:
color voltage (Volts)
IR 1.5
red 2.0
orange 2.0
yellow 2.1
green 2.2
true green 3.3
blue 3.3
white 3.3
UV 3.3
blue (430 nm) 4.6
Remember to use at least 14v as a design voltage..
RF REMOTE CONTROLLER RGB LED is also nice for a bit of lighting effect should you purchase a roll of RGB LED instead of a single color. I feel the RF controller is better deal than IR as you don't have to have line of sight for it to work...
Or control 3 separate single color circuits with just one RGB controller.

But higher cost. Make your decision on what light output you want. Also color temperature makes a difference.
The florestent lights I have put out 900 + lumens
Are there any led tube lights that have this light output ?

Unless you are a serious dry camper and have to watch every amp being used, I would just get a dual tube fluorescent light. They put out a lot of light and are much more efficient than standard bulbs. I still don't think led's are where they need to be as far as color, longevity, and price.
I certainly would agree that led's have their place and I wouldn't buy a flashlight that wasn't an led light. But for overall lighting...forget about it.

I replaced my 12 10W halogen hockey puck with 200 Lumen leds from Ebay. Look for 15X 5050 on the disk and current limit circuit on back. Mine were made by Flight and were $7.00 each. I'm happy with the change.

I ordered those lights from China off Ebay for about $7 for two. Installed them in the RV today. My initial opinion is they might be whiter but not brighter. But they are cooler and use less power. Not sure the less power is worth persuing.

My batteries of mini caravan no longer take a hit no matter how badly my kids and DW abuse the lights. I don't stress about it and we all have a nicer weekend.
