Gardner Tritium-MAX Isotope 22.5mm x 3mm


SKU: N/A Category:


These ‘Large’ Tritium Max isotopes offer the highest light output in all colours compared to the smaller (lower volume) Betalights made using the same processes.

The size and high output makes these isotopes ideal for mounting on rod tip adaptors to show movement of the rod tip, in large bobbins or indicators to offer the best possible visibility.

  • There is 1 x Tritium-MAX Large Betalight / Isotope per pack.
  • Available from BFW in colours: Ice Blue and White
  • Size: 22.5mm x 3mm

Tritium-MAX Betalights are the ultimate continuous light source, providing the maximum possible brightness. The tritium gas mixture used is sealed into the glass tube under maximum pressure, making these the most powerful isotopes available.


The light output of any Betalight is governed by two main factors, the first being the final colour of the light emitted by the Betalight; the second being the total volume and pressure of the gas that is trapped inside the glass tubule. This essentially means that a lower volume of gas at maximum pressure will never be as bright as a larger volume of gas at the same (maximum) pressure.

Each individual ‘colour’ is created by blending different Phosphorous compounds into the Tritium gas. Consequently, there is always variation between the light output of different colours; with the brightest colours always being green and blue, closely followed by the white. Red, purple and orange Betalights are the least powerful in terms of raw light emission.
