This dual beam, bullet shaped headlamp lighting system provides bright light that lasts a long time. At maximum capacity (2 - 35W bulbs both in use) will provide usable light for about 1.4 hours (we timed it). If you choose to use one light or lower wattage bulbs, the usable duration can be extended significantly. The light thrown from this system is bright enough to announce your presence to oncoming vehicles on the street as well as illuminate a path through an unlit trail. On the trail, I was able to maintain a decent pace without outrunning the coverage of the headlights. On the street I was able to avoid some potentially bad situations with oncoming vehicles turning across my lane. Both are exactly what a headlight is for, which means I am digging this light's performance.
Overall the Marwi Pro-Elite worked exceptionally well. It's easy to mount on your bike or to swap between bikes, with its quick release fastener, It's light weight and it's bright.
Some pretty neat features that the Pro-Elite has are its durable metal casing, its water-sealing rubberized buttons, and its adjustibility.
The alloy shell is tough while remaining lightweight. One gets the impression that this lighting system could take a decent knock without any trouble. The system weighs in at 655 grams, most of which is the battery pack. The light rig is actually very light so, I think the only way to save weight would be to use a smaller battery. But then you have to deal with less burn time…
There are 2 rubberized buttons, one controls the main lamp and the other (obviously) controls the secondary lamp. No contrived or complicated switches, just two simple buttons, this means reliability.
Finally, each lamp can be adjusted independently. You can adjust the upward, downward and side-to-side aim so that you can focus them both at a single point for maximum brightness, or push them apart to get a wide spread of illuminated area.
Now, we took this item out for testing during a deluge and it worked flawlessly. But, I did notice that a bit of moisture got inside the lenses. This didn't impair the function of the lamp but, it could be a potential issue in the future. Though, to be fair, we received this item as a demo, which means it has been used before. It could very well have been abused by a previous tester. And further more, how many cyclists really would be riding in a flood inducing maelstrom? But I digress.
