This is my simple review of a product I purchase off Ebay. They say 115k Lumen, maybe not, but to my point of view, they are bright enough for me. I believe they are china lights, says so on the box. But hey, they are affordable, at around 100 invested and a saterday afternoon. Also they have held up in the direct weather, they sat out in the back yard for 3 months straight while I built the trailer for it. There has been no water intrusion or fogging. Maybe I got a good one, but hey, I took a change due to my budget. Which is normally zero. I'm married and live in a sub-division where every ride is a cost. lol
For reference the fence is 60", the back house is 120'. I ride forest and logging roads. So distance is not a requirement, penetration into the bush is.
To give reference here is regular settings of factory lights;
Here is High Beams Factory;
This is only the 12" brush guard model;
This is the 30" Roof:
Here is all (High Beams, 12" and 30";
I have all additional lights on relays, so no dimming while running. Also I have a dual battery system with multi battery switch.
I hope this help someone, only trying to help.
