Portable Sports Field Lighting

I’m looking for portable lights to light up an ultimate frisbee field (90 yards long x 40 yards wide) at night. My friends and I play at local public fields. And I’m looking for a way for us to play later into the night. At the moment, this is just a fun little project.

I figure I will probably need 4-6 light stands. Each light stand will probably need to be 10-12 feet high to avoid looking directly into it when running around on the field. I’d like to keep the cost to less than $100 per stand, although I’m flexible. I’d like the run time to be 1-2 hours. Here are a couple of approaches that I think might work.

1. Buy a bright, floody flashlight, like a BLF Q8. And then buy a tall tripod to hold it. For tripod options, there are the following: Ravelli ALS – 10 foot tall light stand for $30 Ravelli ABSL – Two 13 foot tall stands for $100 Make a homemade stand out of PVC pipe or tent poles MegaMast – 28 foot tall tripod for $700 (not really an option, but interesting anyway)

2. Buy an off-the-shelf light stand like a Milwaukee light stand.

There is no AC power at the field. And I don’t own a generator. So any suggestions that include AC powered lights would need to include a suggestion on a small, inexpensive generator.

I think I’d highly prefer the flashlight route. That way it can be dual purpose: awesome flashlight and light stand. I also like that the batteries are standard and can be replaced. So they can be dual purpose as well. It also gives us the option to bring tons of spares if we want to extend our playing time.

Any suggestions are welcome. Thanks in advance!

My first question would be, do you really want to do flashlights, or do you want the best way to light the field? The flashlight route is nice because you wind up owning a bunch of cool flashlights, but if you want to light the field for the least amount of $ possible, there may be better options.

If you like DIY, I might do something like this:

Goodwill or other thrift stores are good sources for 12V SLA batteries from uninteruptable power supplies. Combine those with a few large COBs (make sure to get 12V varieties) and you will have lots of Lumens/$, and they will run all night. (although you will need to throw in a heatsink or current limiting resistor so you don’t fry the COBs).

These are less than $10 each, the ratings say 12V 4A (48W) and >100lm/W, so that would be a claimed ~5000lumens each. I have some of the smaller COBs from this store that I bought for a different project and they were fairly accurate with their lumen claims.

Have you seen this Fishing Lamp Car Rod Light ?
Maybe not the nicest tint but a new idea how to install one of sac02’s COBs.
