Step 1:

Caution Caution Caution!

Please read this manual carefully: the Sola 4000 is a professional underwater video 

light which can produce high levels of light and heat, and must be used with care.   

Do not turn your Sola 4000 on outside of the water for more than a few 

seconds at a time.  It is designed to be cooled by surrounding water, and 

may overheat if it is not adequately cooled.  

Never look directly at the Sola 4000’s LEDs when turned on.  

The Sola 4000 has a hard off switch or Mode Switch that completely 

disconnects the battery from the circuit for travel.  In addition the LED 

plate can be removed if required by airport security.

Step 2: 
First-Time Assembly/Travel Safety Features

Your Sola 4000 will ship to you with the LED plate turned backwards, and the Mode Switch 

set to “Travel” (the airplane icon).  This is the recommended method of travel with your Sola 

4000 to comply with the strictest aviation regulations.

Connecting the LED plate

1. 

Unscrew the silver threaded bezel and remove the LED plate.  

2. 

Check the o-ring and sealing surfaces of your Sola Nightsea LED plate for any 

debris and be sure there is a light coating of silicone grease on the o-ring.  

3. 

Flip the LED plate and position it so the pin on the body mates with the hole 

on the back of the LED plate.  

4. 

Press the LED plate into place, and screw the bezel back on securely.

Dive/Travel mode 

The Dive/Travel mode switch physically disconnects the Li-Ion battery  from the 

circuit. To connect the battery, turn the dial so that the groove points at the scuba 

diver icon.  The light will be ready for use but will remain off.  
Slider Switch

The Slider  Switch activates the light, and controls brightness.  It can also be locked 

into place to by centering the slider and rotating the switch 90 degrees in either 

direction.

Step 3: 
Charging the Sola 4000

Note: The Sola 4000 will not charge unless the 
LED plate is connected. 

To charge:   Turn the Mode Switch to Dive mode and 

connect the charger to the back of the light head.  The 

rear display LEDs will light up left to right to confirm 

the light is charging and the battery icon will indicate 

the charge level.

Step 4: 

Operation

Turn the Mode Switch to Dive.  Unlock the Slider Switch, and tap it forward or back.  The 

light will turn on in the level 4 position (1500 lumens).  Do not leave the light on for more 

than a few seconds  in air.

• Tapping the switch forward while the light is on will increase the brightness level 

until it reaches the highest setting (power level 7). 

• Tapping the switch backward will decrease the brightness level until it reaches 

the lowest power setting (power level 1).  

• Holding the switch in the forward or backward position for two seconds will turn 

the light off.

SOS Mode

From off: hold the Slider Switch back.  The light will come on as usual, but 

continue holding for four seconds and SOS Mode will be activated.  Release 

Slider. 

From on: hold the Slider Switch back.  At first, the light will turn off, but after 

3 more seconds, it will come back on in SOS mode. 

Turn off SOS mode by holding the Slider Switch back for 4 more seconds.

To change from SOS to On, tap the Slider Switch forward.

Accessories and Extras

Cyan Filter Wheel - 

(800-0162)

The Cyan filter matches the Sola 4000’s light to the color of the 

ambient sunlight.  This allows you to shoot images using the same red 

filter on your camera lens as you would use to shoot in the ambient 

light, making it possible to shoot scenes with the foreground and 

background matching in color.  The filter screws into the filter wheel 

using a standard 37mm filter thread, making it easy for you to insert 

your own custom filters.
