How many lumens?

[chim]

1 - Lies, lies and more lies about brightness, power and lumens. Bigger numbers sound better.

2 - Been running LED's for more than 10 years without any failures.

3 - Aiming won't eliminate blinding others. An area can be illuminated well, with adjacent areas appearing to be somewhat in darkness. Go stand in the "dark" area and see "if'n it don't burn yore eyes".

4 - I think some people install light bars because they like to say the name. "Mounted my light bar sounds more impressive than "put lights on my tractor".

5 - Unless your name is Juha Kankkunen you need floods and not spots.

Here's some info:

• Incandescent: 1 watt = roughly 15 lumens
• Halogen: 1 watt = roughly 20 lumens
• CFL (Compact Fluorescent): 1 watt = roughly 70 lumensLED (Light Emitting Diode): 1 watt = roughly 80 lumens

If 1 watt of halogen light = 20 lumens, then the OP's four halogen lights that total 12000 lumens would draw 600 watts or 50 amps. That's more than the 35 amp OEM alternator on his MF 1759 tractor can produce???

light on rops has to be on top with the bar up, or you will be blinded terribly. I just did this and even with custom blinders made, its not great. it needs to be above your head.

John Deere disagrees. They mount all of their lights at shoulder height. Never been a problem for me, or tens of thousands of other users.

Yep. This wasn’t an uncommon problem, back in the day. That’s why old sealed beam headlights were only 50-60 watts.

Hes claiming the led’s put out 12,000 limens. Thats 150 watts at 12 v, so about 12.5 amps.

But ive run into so many claims about lumens that dont match what a meter shows is true output. Plus, shining a meter directly into light fixture is not true measure. Proper guides would test output at a certain set distance from fixture.

My error. I read the OP's post to mean the halogen lights on the tractor put out 12000 lumens. Halogen lights produce 20 lumens per watt. 12000 lumens divided by 20 lumens equals 600 watts divided by 12 volts equals 50 amps.

Your math is much closer. LED's produce 90 lumens per watt, so 12000 lumens would require 133 watts or 11 amps.

My flood lights are mounted with magnets. In the woods I flip them under. Forward for driving and using the front end loader. Backwards for snowblowing

have a photo of these thousands of tractors cus google is failing me

I have lights on my cab going to take the bulbs out and check for a led replacement. The lights on the
hood thinking about adding a bracket to add an led on each side
and use the wire from the hood lights just to get the lights over the bucket and the hood lights will be decoration as they won't work.

Someone said that the on coming cars don't dim their lights? Back in the mid 70's my friend who travels a lot at night had the same problem so he mounted an aircraft
landing light in the middle of his pick up he said people would flash their lights blow their horn but he never turned it off until he was past them some even stopped in the middle of the road. And yes it was illegal but it worked
