The RD series is our Recreational Diving light range for those needing a reliable dive light, with high build quality, and added features at an unbeatable price. When used for guiding, or photography, screw in a filter (designed specifically for the RD90T) and you can change your color in seconds.
The RD90T is a powerhouse as a primary light during the day to peak under reefs and ledges, or at night when you are trying to spot your favorite fish. The tight beam is bright enough to signal other divers, or focus on a subject when filming. If you are on a low-budget and need a reliable light source, the RD90T is our main selection.
Same as the RD80, the LED button switch contains a color changing battery indicator. The push button features a High, Low, and Strobe function with a hidden stepless dimming function.

All Video and 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.
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.
