How to Charge Glow Discs for Disc Golf (365nm vs 395nm)

Practical tips for glow rounds: wavelength, charging time, and how to get a strong, even glow.

← Back to English home Norwegian home
Quick answer:
  • 365nm often charges many glow materials very efficiently, but can require better LEDs/optics and is usually pricier.
  • 395nm is common, affordable, and still works very well for glow disc golf.
  • Consistency (close distance + even coverage) usually matters more than exact timing.

Why wavelength matters (365nm vs 395nm)

UV light excites the phosphors in glow plastics. Different glow compounds can respond a bit differently, but for disc golf you’ll usually see strong results with both 365nm and 395nm — especially when the UV source is close and consistent.

What I use (385–395nm) and what I see in practice

My DiscCharger setup uses UV LEDs in the 385–395nm range (some sellers list it as 385–395). In real glow rounds, a short time at close range is typically enough to get a long-lasting glow (depending on plastic type).

How to charge glow discs (step-by-step)

  • Keep the UV source close to the disc surface (distance usually matters more than duration).
  • Ensure even coverage across the whole flight plate, not just the center.
  • Recharge between throws if needed (some plastics fade faster).
  • Repeat consistently—a predictable charging workflow is what keeps glow strong over an entire round.

Flashlight vs charger in a bag

A UV flashlight works, but it’s typically one disc at a time and requires active use between throws. A bag-based charger creates a smoother workflow: multiple discs charging at once, more even exposure, and no need to handle a flashlight between throws.

Tip: If your glow seems weak, it’s often not the wavelength — it’s distance, power output, and how evenly you cover the disc.

Will constant UV in the bag damage discs over time?

Normal use during glow rounds (hours, not days) is not expected to cause noticeable wear. Like any plastic, extreme long-duration UV exposure can contribute to aging over time, but typical glow-round use is far below that level.

FAQ

  • How long should I charge a glow disc? Often just a few seconds at close range, but it depends on plastic/glow compound.
  • Is 365nm always better? Not always — 395nm can still be excellent for disc golf glow rounds, especially with a consistent setup.
  • What matters most? Close distance, even coverage, and repeatability between throws.
