Stepless Dimming

  All Primary and Video/Photo lights from Scubalamp feature stepless dimming; hold       the switch, and it will dim in increments of 10% until you reach your desired     illumination. Press button again, and it will go back to a preset high or low mode.

The body is made from machined aluminum and solid glass front protects the LED from damage. Double O-ring sealed and user replaceable battery. 

Either way, as a primary light, this thing is bright and durable. 

The battery is compatible with the PV32T as well. We recommend the RD80 as a suitable backup if looking to streamline your profile.  We do NOT recommend operating this light outside of the water for more than a few minutes.

The body is made from machined aluminum, and 4mm solid glass front protects the LED from damage. Double O-ring sealed and user replaceable battery.  

NOTE REGARDING LIGHT CIRCUITS and RATED OUTPUT:

All Scubalamp lights use constant current (continuous output) drivers; unlike other brands that use a variable output with 'Big' claims. What this means is that you will achieve full rated brightness until the battery reaches around 30%. Following, the light will dim to preserve the remaining battery life. 

A light that does NOT use a constant current output driver will begin to dim almost immediately. It will continue to dim as the battery is depleted and the voltage drops. This means that a light rated at 2000 lumens, will only be around 1500 (or so) within the first few minutes. Buyer beware of large output claims for the rated batteries. This is one of the main reasons why we recommend our lights in addition to the durability and quality.
