To choose a good dive light, you may focus more on the lumen output, light beam, throw, runtime...Besides, there are also some protective functions and mechanisms on dive lights needing more attention, such as something below.

Heat sink and smart temperature control for heat dissipation
To dissipate heat properly, some good-quality dive lights have a heat sink, also the correct way of the light diodes mounting, encapsulated in a housing. Besides, the smart temperature control on the light also plays an important role, such as xtar D20 1000 dive light, when temperature within rises to 55°C or higher, this dive light itself will reduce brightness to ensure its normal function, which protects the light from being damaged by high temperature.

Anti-reverse circuit connection to protect user’s safety
Anti-reverse protection is a user-friendly design, and also extend the dive light’s lifetime. If the user reversely place battery's positive and negative electrodes by accident, it will be safe and prevent damage to the light.

Solid housing material and proper oxidation
Some dive lights are constructed with aviation aluminum materials, coupled with military-grade class III hard-anodized finish. These kind of dive lights will have high performance of anti-corrosion, anti-abrasion.

Gold printed springs
The gold printed springs prevent oxidation, improve efficiency and have better conductivity, also avoid poor contact.
