Just received my Lumapower MVP from battery junction and was very excited to try it. Read the instructions to the letter, charged the ultrafire batteries, inserted the batteries, hit the on switch and, nothing! Tried it again, still nothing. Anyone else having trouble with this model or brand? It looks extremely well made but it doesn't work. I even tried the paperclip to the battery trick still not working. I think the problem is with the tailcap switch. Any ideas or thoughts?

Are the batteries backwards?
If they are, you might have fried the circuit. After frying the circuit, the light won't work anymore.
If you put the batteries in the right way and the light doesn't work, get a replacement.

I've fried a light that way.
don't have a lumapower MVP, but, if you can get near the circuitry...
take a deep whiff xD
if it smells burnt, you probably put the battery in backwards...

Are your batterys "flat tops" or do they have a "nipple"? The MVP needs a screw installed IIRC @ the + end to make contact with the + end of flat top batteries.

If they have a nipple, then thats not the problem. Lumapower recesses the positive contact in the light so as to provide reverse polarity protection. If you are to use a flat top battery, such as a Li-Ion, they provide a brass screw to insert in the positive contact area of the light so it will make contact with the battery.

I had my MVP for a month or so before the switch went out. Battery Junction replaced the switch with no hassles. No problems since.

Have you confirmed that your ultrafire 18650s are in working order?
Do you have another light to test them in? Do you have a multi-meter? Check make sure you are getting ~4.10-4.20V on your freshly charged 18650s.

Thanks for all the good suggestions. Unfortunately I don't have another way to confirm the batteries are fully charged. But I also tried the MVP with 4 CR123A's just to see if it would light, but it didn't. Looks like I will be sending it back for a replacement!
Just a quick update on my MVP. I sent it back to Battery Junction, they inspected it, and discovered it had a faulty LED engine. They replaced it and I am getting it shipped back to me. Anyone have any ideas why the LED engine would fail, especially on a new out of the box flashlight?
