Gardner Tackle Products



Tritium-MAX betalights are the ultimate continuous light source. Gaseous Tritium technology provides the maximum possible brightness making these the most powerful isotopes available. Tritium-MAX are also the first betalights (for fishing use) to be made in True Purple colour.

  • Large (22.5mm x 3mm) – for use as rod tip indicator or on some bobbins.
  • Small (12mm x 2mm) – for most buzzers, rods and accessories, also Bug Indicators.
  • Bug (10mm x 2.5mm) – fit all Bug Indicators apart from Nano Bugs.
  • ATTs (6mm x 2mm) – tiny size for ATTs Alarms and Nano Bug Indicators. Sold in Singles (Nano) and Pairs (ATTs). These betalights are glue fitted into the ATTs Alarm betalight slots.
  • Available in colours: Green, Red, Ice Blue, Purple, White, Orange and Yellow (ATTs and Nano only).
  • Betalights are glue fitted into the Gardner Bug Indicators.

Fitting the Bug Betalights:

The Bug indicators come in two formats.

The coloured Micro and Mini Bugs have an internal stem that the Betalight is glued into underneath the coloured lens.

The solid white bodies, carbon style and black bodies all have a milled slot on the front into which the Betalight should be glued.


The light output of any Betalight is governed by two main factors, the first being the colour of the Betalight and the second being the gas volume/pressure.

Each individual colour is created by blending different Phosphorous compounds into the Tritium gas. Consequently the brightest colours are always green and blue, closely followed by the white. Red, purple and orange Betalights are the least powerful in terms of raw light emission due to this phosphorous mixture.

The brightness of any isotope is also directly proportional the volume and pressure of the Tritium Gas inside of the sealed glass tube. 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.

Colours Large (22.5mm x 3mm x 2) Small (12mm x 2mm x 2) Bug (10mm x 2.5mm x 2) ATTs (6mm x 2mm x 2) Nano (6mm x 2mm x 1)

    Hello! I’ve bought a number of your Betalights in GB and they are just great!!! I’m wondering if you could ship me more here to Hungary? Can you ship them to Hungary (because of laws)?

    Thank you very much!!!

    How do I fit the isotope in the bug, inside or on the outside and what is best to use?

    • Hi Vernon,

      The Bug indicators come in two formats.

  3. Hi, I bought 3 beta lights in feb and was wondering just how bright are they supposed to be? As mine just give off a dull glow is this right or are they supposed to be really bright?


    • Hi Lee

      Betalights give off a much duller light than a chemical light, but rather than only lasting a couple of hours they’re working life is measured in years.

      They are made from a glass tube filled with special gas. This means that if the tube cracks and the gas escapes they will loose their effectiveness.

  4. ive glued my betelights into my micro you need to snap them first,like you would a glow stick because they hardly light up even in the dark.cheers

    • Hi Mike

      If ou try to bend them the glass tube that they are made form will break and the gas inside will escape.
      The Tritium Max betalights are made to be as bright as they can be given the volume of the inside of the glass tube and the pressure of gas that has been pumped into them…

  5. Hi Gardner,

    I have just recently purchased a set of atts and by reading other posts on here am guessing the only way to fix the atts beta lights is to glue them into the ears?

    Now im looking at buying a set of nano bugs to complete my set, how do the beta lights fix into these, are they also glued ?

    Thanks, Ross

    • Hi Ross,

      Yes, they must be attached with glue as well.

  6. Hi, i have the atts bite alarms and want to buy the bug indicators for a nice complete set.
    I am looking at the micro bugs, but which size tritum-max betalights are best fit – the small ones, or the specific bug size?

    • Hi Russell,

      The Bug Tritium Max would be the best fit.

  7. Hi Gardner,
    I would like to ask about quantity of betalights per pack in Small and Large size? It is one betalight or 2 betalights per pack?
    Many thanks

    • Hi Ladiis,

      It is 1 Betalight per pack for the Small and Large size.

  8. Hi

    I have just puchased 4 ATTS alarms, 4 mag rollers and Receiver in purple. I hope that the carp look as good as my set up. lol. I also have the beta lights to fit the alarms. Can you suggest the best way of fixing then to the ears.
    Many thanks

    • Hi John

      These ATTs Tritium-Max betalights need to be glued in position in the ears of your ATT heads – so really what you need to choose is the best glue to use…

      If your really careful you can do a nice neat job with just a bit of Rig glue but be careful not to get any around the outside of the slot as Rig glue tends to go white when it dries – we don’t want your nice new ATTs to end up looking scruffy do we!

  9. Hi do i need to do anything to activate the betalights?
    i bought a blue one and tried it in my microbug on a night session at the weekend and it hardly glowed at all and i couldnt see it at all once i moved more than a couple of feet away.
    thanks Lee

    • Hi Lee

      You don’t need to ‘activate’ betalights – they should be glowing unless the glass they are made from has been damaged – otherwise they have a usable life measured in years..

      The power output of any isotope is directly proportional to 2 main attributes – the volume of the inside of the sealed glass tube and the pressure that the Tritium Gas is inside that tube. The volume of the small tritium max’s is small so even at maximum gas pressure they will never be as bright as a larger higher volume isotope.

      The only other factor is the colour of the betalight – the brightest colours being green and blue, closely followed by the white – with red and orange being less powerful due to the phosphorous mixture used with the Tritium gas to crate that colour. Having said that – they should still be visible (especially the blue one).

  10. hi
    im interested in purchasing betalights for my atts can you tell me what the life span is thanks

    • Hi John,

      The expected life span of a betalight is around a minimum of 10 years.

      Hope that this helps.

  11. How long do they last?

    • Hi Aaron,

      A minimum of 10 years, as long as there is no crack allowing the gas to escape.

      • Fantastic, thanks for the quick reply

        • No worries Aaron, glad to help

  12. Hi there, I’ve owned 2 pairs of “bugs” before, however, I’ve found that the green ones glowed much brighter than the orange ones, I was wondering if you could advice on which one is brightest of all the colours? Thank you.

    • Hello there Aaron,

      Yes, green is naturally the optimum colour for maximum uL (micro Lamberts) output, due to the gas mixture. Closely followed by purple and then white and orange. I hope that this helps.

  13. does the small betalights fit the gardner tlb alarms
