Compare the DGX 300 - 600 - 800 lights

• The DGX 300 Mini Light features a true out-the-front 300 system lumens (600+ raw LED lumens) with 30 minute burn time using a rechargeable 14500 battery. Using a quality AA size disposable alkaline battery you will get about double the burn time with half the lumens.
• The DGX 600 Handheld Light features a true out-the-front 600 system lumens (1100+ raw LED lumens) with 60 minute burn time using a rechargeable 18650 battery.
• The DGX 600 Button model is also available in a VIDEO version that features a diffused no-hot-spot 120° beam perfect for use with underwater video, but is otherwise identical to the tight 8° beam version.
• The DGX 800 Handheld Light features a true out-the-front 800 system lumens (1100+ raw LED lumens) with 90 minute burn time using two rechargeable 18650 batteries.
• The DGX 800 has a longer body incorporating two batteries means the increased power of the DGX 800 is 30% brighter with 50% longer burn time.

The DGX 600 is available in your choice of BUTTON or TWIST style activation. The choice between twist-on or button-on styles is mostly a matter of personal preference, although the TWIST version has a ultra deep depth rating. If you are mounting the light, we recommend the BUTTON style. If the light is being carried as a handheld backup to a primary, we recommend the TWIST on style.

Various LED dive light suppliers use different methods of determining light output, plus expressing them in different forms of measurement. What matters is the visible light from the LED that bounces off the reflector and passes through the lens. The quality of the reflector and lens, as well as the actual amount of power delivered by the battery have a major affect on the amount of light that reaches the target. Dive lights would be better described by the system lumens (sometimes called out-the-front or OTF lumens), which is the amount of visible light emitted by the entire system of battery, bulb, reflector and lens. Describing any LED dive light in terms of the radiant lumens specification of the entire light output for a raw LED module (including IR and UV wavelengths we can't see) at maximum power under laboratory conditions can be very misleading. Unfortunately we have to mention the radiant lumens value because most other dive light suppliers use only the bigger number to inflate their descriptions.

The DGX800 light has a driver working voltage from 3.0V to 13.0V, and thus is suitable for use with its two battery body. Our DGX600 series light heads have a working voltage on the LED driver of 3.0V to 4.2V, suitable for their one battery body. Although they look similar and will fit together mechanically, the DGX600 light head must NOT swapped on to a two battery body. If you mount a DGX600 light head on a two battery body, the electronics in the DGX600 head may burn out and then light will no longer come on.
