I just low balled him at $160 and he went for it. he wanted $250 for four of them and I told him not a chance, if he gave me a good price and I like the lights that I would be ordering more. Shipping was extra but it was very fast as I ordered something from OK, and these lights came from Australia and the lights arrived before the package from OK,USA.
They are fairly rugged, I was bush mowing a field with lots of spruce trees in spots and the branches were hitting them and no problem. I know it is not a lot of impact but when I drive on the road to get to another field the road is full of pot holes and they smacked together a couple of times before I tightened the mounts up and they did not crack.
In the pictures the rear lights I have pointed down and they shine on the equipment that I have behind me rather than shine straight out. But as I mentioned I have to block the driver inside of the lights as they shine in your eyes when you turn around to check your implements.
I will post some pics of how I fixed this problem later today.
Have a look on Ebay there are others that sell the same light. These have 2000 Lumen but I seen a slightly cheaper set with 1950 Lumen. They are from China and if that does not matter it is only for two of them.

Try to stay with at least 1750 Lumen or higher, I have tried lower rated ones and they don't seem to carry as far. You can get flood, wide flood or pencil flood lights
I have wide flood and I find them great, I tried the pencil beam and it would be nice to have if you had flood or wide flood as it just casts a light straight out. Not great for an all around work light.
Something else you might want to consider is replacing your stock headlight with led ones. My tractor takes a 894 light bulb and I just went to Ebay and typed in 894 led and it shows the replacement.
HID lights are too much work as you need a place to put the ballast, and on my tractor I just could not find a place to put the ballast that it was not exposed to the weather or heat.
Be sure to post some pics when you manage to get it worked out. Let me know if I can be of any more help. I don't mind
