Looking for something different? Tired of night diving? Fluorescence will give you a whole new perspective on the world beneath the waves. With Tonelife excitation and barrier filters, you can convert your existing lights into a fluorescence set-up. No need to purchase expensive specialty lights or guided dives. Be the explorer!
Why yellow mask filter? This is because unlike UV, blue light is not invisible to the human eye; without the filter you will therefore not be able to see the fluorescence because it will be overwhelmed by the ambient light.
