Those Luxion lamps are impressive in the light out put they give but are not a cheap way of getting lots of light. What is also important is the battery life aswell.

I have twin 5 watt luxions and at high power I get 2.5 hours of blinding light. At low power- I can get 8 hours of light but low power is not used that often. Now if you are looking for an economical lamp that gives out light- then look at the Halogen lamps.

Don't know what it actually means but the luxion 4 watt leds only put out 85 lumens of light- The 20 watt halogen puts out 390.

I use a Use Exposure and one thing it has in common with the Vega is that it is a self contained lamp. That is a godsend- no separate battery or leads to lose connection with.

Depends on how well light your route is- But don't take the Vega offroad- It will not be powerfull enough. Mine is.
