The Gemini 500R Monolight from Bowens is an ideal choice for both studio and location photography. A classic, dial-oriented design gives immediate access and control to 500Ws of power variable over a 5-stop range. Control of the bright 250W modeling lamp is equally intuitive allowing you to select output that's proportional to the flash power level, full on for easy focus, user selected light level and off. Monitor your settings on the large digital readout. The 500R recycles in 1.3 seconds to full power and alerts you with an audible beep and ready light.

While you can trigger the flash with the included sync cord and adjust flash functions from 23' away with an optional remote control, you can also take advantage of the 500R's capacity for wireless triggering from distances up to 80' by purchasing a Pulsar Tx Radio Receiver and a receiver card that plugs into the body of the flash.

Location shooters will appreciate the 500R's DC capability allowing 150 full power flashes with Bowens' optional small Travelpak battery power supply, 300 flashes with the optional large Travelpak and thousands of flashes with both at reduced power levels.

Take Control

The Gemini 500R is wireless compatible with purchase of a Pulsar Tx Transmitter and receiver card for remote triggering at distances up to 80'. On a smaller scale, flash functions can be adjusted on overhead units with an optional remote control.

Location Shooting

The Gemini 500R can be powered from AC mains power in the studio or by the optional Bowens Travelpak battery system which is able to provide power to two Gemini lights. Using the 500R with the small Travelpak will provide up to 150 full power flashes per charge. Double that with the large Travelpak.

Smartcell

The built-in photocell on the Gemini 500R has a Smartcell option to enable pre-exposure flash management allowing the Gemini head to be synchronized to the camera shutter on the 1st, 2nd, 3rd, or 4th flash.

Metal Construction

A tough metal housing protects the flash head's sophisticated circuitry and high powered capacitors from knocks and bumps which are routine in hard working studios and during transport.

Lamp Saver

The Lamp Saver function automatically dims the modeling lamp after a user-defined period of inactivity to extend the life of the lamp. This combined with the soft start technology built into the Gemini 500R means less money spent on replacing modeling lamps.

S-Type Accessory Mount

Adopted by many flash manufacturers, the 500R's S-Type reflector mount allows you to take advantage of numerous accessories outside of the Bowens line.

What is the power supply required.? can we plug it to a 240V A.c.?If not, pls confirm u have variants to use for 240V
Asked by: Anonymous
Unfortunately, these monolights are only compatible in 90-130 VAC. A multi-voltage option for use in 240VAC is the Bowens XMS500 2-Light Flash Kit B&H # BOBW5330.

question

I have enough light stands and umbrellas. So can you substitute them for two Bowen S mount softboxes 24x36 and 8X36 if I buy this kit?
Asked by: Zia
I don't believe so.. because the bowers Gemini 500R comes as that kit already. You would have to purchase that separately. The other choice is to buy the next generation bowens kit. I hope this helps?

high speed sync over 250 sec?
Asked by: Perry
High speed sync? No.However using pocket wizards you can achieve Hypersynch of shutter speeds above that. Course how high you can go will depend on your camera and it's shutter. Pocket Wizard has a wiki that goes into details.

question

Can the Bowens Gemini 500r capable of performing High Speed Sync over 250 seconds?
Asked by: JACKIE M.
Unfortunately, the Bowens Gemini does not offer high speed sync capability. To work in high speed sync over 1/250 of a second, you may want to consider the Interfit S1 monolight, B&H # INS1. Besides this feature, the monolight also offers TTL functions with the help of the S1 TTL Remote for Nikon or Canon. Please see the image below.
