Let me know how everything is please
I used them for a quick toss around the disc golf course today, and they have their plus and minuses.
Pros:
-thin and tape on easily
-they have a blink-mode, but I don't really see any purpose for that
-about 1/3 of the cost of bobber lights
-available in many different colors, which looks really freakin cool when you put two different colors on a clear disc
Cons:
-they shine bright only in one direction (top), they shine about 50% strength through the bottom, and don't really shine at all out the sides
-definitely do not look waterproof
I only attached them to a decently clear blue Z-plastic Wasp (used the clear/white lights) and to a perfectly clear CryZtal Challenger (red on one side, green on other). They were plenty bright on the clear putter, but not so bright on the blue Wasp, and it was actually somewhat difficult to track it once it got to around 250-300'. If it was a driver it would have been even more difficult to follow it the entire way. Although, once I walked to the area it landed it was pretty easy to spot. I think it would have been more visible if I taped one light facing down and one up, instead of facing them both up, because while it's in flight I'm actually looking at the bottom of the disc and that's the direction the lights were shining at only 50% power.
So in conclusion, the bobber lights shine brighter in more directions and are water-proof. These wafer-lights are less expensive, available in more colors, and tape/stay on slightly better than bobber lights. They both weigh about the same. They will work on slightly tinted discs, but work much better on completely clear discs, and if you're throwing over 350' a clear disc may be a necessity.
