General:

FluoMedia.org provides you with high quality gear and lots of information and tips for fluorescence diving.

See the page about technology for an explanation of how the products listed below work and interact.

Our philosophy:

Our most important motivation is to help you to experience the stunning and fantastic world of underwater fluorescence.

We aim to be less expensive and yet to offer better value than other manufacturers.

Contrary to most other vendors we experiment a lot and test our own gear extensively in order to fine-tune it for optimal results.
See for example our collection of beamshot videos.
We do this out of passion for underwater fluorescence and for fun, no matter the costs.
This would simply be too expensive for other manufacturers to do.

R E A D    M E    F I R S T:

The state-of-the-art technique for observing underwater fluorescence uses blue light, not ultraviolet (UV) or black light (see UV vs. blue for the reasons why).

The minimum equipment you will need in order to observe underwater fluorescence is: (1) a blue light dive torch and (2) a yellow mask filter
(because unlike UV, blue light is not invisible to the human eye; without the mask filter you would not be able to see the fluorescence)
and (3) a mask strap wrapper for protection and loss prevention of the mask filter.

For photography or filming you will also need (4) a camera filter.

See the (5) order page for information about placing an order.

Please note that our torches and filters are carefully tuned to complement and match each other's properties.
Mixing fluorescence diving equipment from different manufacturers is therefore likely to give frustrating results.

Prices:

New prices (as indicated below) are effective starting on the 1st of January 2016.
These new prices will not affect orders which have been placed before this date.

Please contact us for the most recent lowest available prices!

Torches: (1)

Listed here are only state-of-the-art fluo dive lights, emitting blue light of ca. 450-470 nm and with a built-in dichroic blue-pass filter, sorted by price in ascending order.

A list of torches which do not all satisfy both of these two criteria can be found here.

Don't forget to also visit our bargains section with discontinued yet fully functional and heavily discounted torches.

[BlueBright 1]

Read the testimonial from Ties Lahlali (founder of UV Dive Koh Tao) to see what he thinks of this torch!

"Blue Extreme" Torch Kit

 
[Blue Extreme 1]
[Blue Extreme 2]
  • This torch is our new "Big Dog" unit emitting a whopping 50 watts of power in the blue portion of the spectrum. With the 150 degree beam angle and flat/uniform image intensity, this torch can light up the entire reef for amazing wide angle and distance shots. Obviously you need the clear water visibility to achieve that but if you do, this torch can handle it.

  • This is a canister style setup that uses a standard ball mount for the head and the battery pack can be mounted on your BCD or any other place on your body. We also make a ball mount assembly for the battery pack to mount on the camera. This is a custom piece so contact us if you have interest in that type of battery pack mounting. The unit includes high energy density lithium ion batteries good for about 2-3 hours depending on the brightness setting, a charger and aluminum carrying case. It has a magnetic switch with three intensity levels so there is no "twist to flood" switch mechanism to worry about.

  • Depth rated to 100 meters

  • Price: $699.00 plus shipping

Mask filters: (2)

 
[Standard Mask Filter]
 
[Standard Mask Filters]

Download the outline of our mask filter (see also the photos on the left); print it without rescaling and check it against your mask to see if it fits (this filter has a very large surface area and should therefore fit most dive masks, except maybe those masks whose nose pocket is very broad, or single-lens masks).

Includes a standard rubber band strap with clips (see the photos on the left) and a mask strap wrapper (see the upper photo on the left). Other straps (e.g. Velcro straps) are available upon request.

Price: €35 per filter/wrapper combo

Each mask filter comes with a mask strap wrapper (3) for preventing loss under water and for protection during transport and storage above water. Without the wrapper you will lose your mask filter in no time (speaking from our own dire experience, and that of some of our customers)!

Beware: Do not don your mask with the mask filter already in place (over your mask), but instead leave the mask filter dangling (secured by the mask strap wrapper) and place it over your mask only after putting on your mask over your face - otherwise you may break the mask filter (the narrow bridge above the nose must not be subjected to strong forces).

Accessories:

Mask strap wrappers: (3)

[Mask Wrappers]

Mask strap wrappers are made from fluorescent neoprene and serve multiple purposes: wrapped around the filter's and your dive mask's straps at the same time, they prevent you from losing the filter during the dive. Since the wrappers are equipped with Velcro along one edge, they can be opened and closed easily, without having to detach the mask's and filter's straps every time. Wrapped around the filter when stored or traveling, they protect the filter against scratches and other damages. Thanks to their different fluorescent colours, they can also be used to identify divers or buddy teams (with the same colour) at a glance during a fluo-dive.

Available colours: fluorescent orange, fluorescent green

Price: €10 per piece

Velcro straps:

[Velcro Straps]

Velcro straps (for mask filters) can be more comfortable to handle (i.e., faster and easier to adapt in length, especially under water) than the standard rubber straps. However, the Velcro straps are less elastic than the standard rubber straps, only the neoprene middle part is slightly stretchable.

Available colours: blue, yellow

Price: €5 per piece

Fluorescent markers:

[Fluorescent Markers]

Fluorescent markers can be used to mark points (e.g. corals) of interest during the day, in order to make it easy to find them back at night

Particularly helpful in scientific surveys
