I think the crowd I play with could be considered night experts somewhat. We crave the frosts of winter so the skeeters will die down. When that happens off we go. I have played 3 rounds in one night to find my windshield frosted over when finished. With that said, the humidity is super high here even in winter so we have tried all the tricks. We also have some water hazards and tons of trees and very dense roughs.
Here are my experiences:
1. Glow discs suck, regardless of who makes them they have to be charged constantly and if the moon is up they can be hard to find in thick terrain.
2. Regular glow sticks and fishing lights are not a great choice either. The sticks don't make enough light and the fish lights are too big(oh and they are expensive).
3. The light's you punch a hole in your disc for suck too! We started here and ruined some great discs for a marginal product. The thing pops out of the disc more often than we like and the light goes off all the time, unless you put foil in between the batteries.
The best setups for night disc golf is this: clear duct tape(expensive but great product, leaves a residue though), flat watch batteries 2032, red LEDs. Put the leads of the LED around the battery and tape to disc. Bottom for clear/champ discs and top for dx/star/esp discs. Weighs in at 4 grams and does make the disc a little more stable, make sure to center the battery in the dimple or over it in a disc. I have knocked one of these combos loose and even loose it still was lit enough to find it. Don't get all LED happy when you go to the sites that sell them, hands down red is the best and consumes the least amount of energy so your batteries can be reused. Find websites that sell LEDs and batteries and if you order from the Chinese/Japanese companies they are really cheap. I think around $0.60 for the whole set up for each disc. You will have to buy in large quantities though, I think 50 of each. Google it or I can find a specific website if anyone is interested.
Recommend the headlamps with the red light option for finding your way around. Use the red only so you don't ruin your night vision. I also carry the roll of tape and extra batts and LEDs just in case and a mag light to shine the basket with, oh and for any would be trouble makers heads. We turn this off prior to throwing. Hooked some guys up in a round in Memphis area with this set up and they loved it.
