Scubapro NOVA 1000R W/O BATT & CHARGER

Lumens measure the total light output, but they say nothing about how that light is shaped, so a tight narrow beam can look far brighter at distance than a higher-lumen wide beam. Beam angle, color temperature, and water clarity affect what you actually see as much as the lumen figure does. Use lumens to compare lights of a similar beam type rather than as a single score of quality.

A primary light is your main light, usually brighter, larger, and with a longer burn time, while a backup is a small, simple light carried in case the primary fails. Any dive where you need a light to exit safely, such as a night dive, calls for carrying at least one backup. Backups are chosen for reliability and simplicity rather than for maximum output.

Burn time and brightness trade directly against each other, so the same battery run at a lower power setting lasts substantially longer. Manufacturers usually quote burn time at each power level, and many lights automatically step down output as the battery drains or the head heats up. Treat quoted figures as fresh-battery, ideal-condition numbers and plan for more burn time than your dive actually needs.

The o-rings sealing the battery compartment are what keep the light from flooding, so inspect them for grit, hair, and nicks every time you open it, and wipe the sealing surfaces clean. Lubricate lightly with the grease type the manufacturer specifies, using a thin film rather than a heavy coat, because excess grease attracts sand. Replace o-rings when they look flattened, cracked, or dry, and do not over-tighten the cap in the hope of sealing a bad o-ring.

Lithium batteries are subject to airline and regulatory limits that vary by cell chemistry, watt-hour rating, and whether the cells are installed or loose. As a general rule lithium cells travel in carry-on baggage rather than checked baggage, with terminals protected against short circuit, but you must confirm your airline's current policy and any local rules before you fly. Carrying the manufacturer's battery specification sheet helps if you are questioned at screening.

Rinse it in fresh water after each dive day and work the switch while it is submerged so salt does not crystallize inside it, then dry it before opening. For storage, remove or charge the batteries as the manual directs, and leave the cap loose so the o-ring does not take a permanent set. Never store a light with corroded or leaking cells inside it.

Test it briefly as part of your pre-dive check, but do not leave a powerful light running in air, because many are designed to shed heat into the water and can overheat on the surface. Check the manual, as some lights have thermal protection that dims or shuts them down when they are dry. Testing before you gear up is far better than discovering a dead light at depth.

It uses a single 21700 li-ion rechargeable cell, which is sold separately on this version (item 30.231.002), along with a compatible charger. Scubapro states the 21700 cell provides 40% more burn time than the battery used in the predecessor model, supporting up to 2.5 hours of burn time at full power. A 50% power mode is available to extend run time further.

Beam shape and LED. The standard Nova 1000R (30.231.002) uses a Cree XPL LED with an 8 degree focused beam measured at 21,000 lux at 1 m, which concentrates light for signaling and inspecting small areas. The Nova 1000R Wide (30.232.002) uses a Cree XML LED with an 80 degree wide beam for broader coverage.

The Nova 1000R is rated to 490 ft (150 m). Watertight integrity comes from double O-ring seals, and an over-pressure valve releases any battery off-gassing from inside the housing. Keep the sealing surfaces clean and the O-rings inspected before every dive to protect that rating.

This configuration includes the Nova 1000R light head and body, an adjustable wrist lanyard and a reusable semi-soft storage box. The 21700 li-ion rechargeable battery and the charger are sold separately, so plan to add both if you do not already own compatible cells. Contact us at 888-701-4017 if you need help selecting them.
