Fluo Diving at Lembeh Resort


November 7, 2017

Have you tried fluo diving? For divers and underwater photographers some of the best dives are the ones with the most color – whether it’s colors on the reef, the corals or the brightly colored fish and critters. If you like color during your dives then bio-fluorescent diving (also known as fluo diving or blue light diving) is an experience not to miss out on.

Imagine the neon lights of any major city or a 1970’s disco and picture that vividness and brightness underwater – that is fluo diving and we offer it right here at Lembeh Resort! It’s not just about the colors though; it’s also about the finer details which you just can’t see with the human eye. Fluo diving also allows you to get up close to fish that would usually swim away under torch light but do not react in the same way to blue light.


 

Fluo diving involves using either a UV light or an LED light with a blue lens and amber tinted eye shields. If you have ever experienced a night dive with luminescence you may understand some of the science behind it, here’s the basics: Certain marine organisms produce proteins that are capable of generating fluorescence when they absorb blue light.


 

The proteins absorb the photon of the blue light which results in an increased energy level, the increased energy is used to emit a photon of light in return with a longer wave length. This longer wavelength is fluorescence and is usually visible as fluorescent reds, oranges, blues, and greens depending on the individual protein affected.


 

Not all marine organisms react in this way but corals are among the best reactors and unveil a myriad of details which usually go unseen, most crustaceans hiding within them will stand out equally as brightly like gaudy baubles on an already overdressed Christmas tree. Nudibranch, cephalopods, worms, clams and jellyfish all react well too. Some fish will react and others won’t but nocturnal species which usually shrink away from torch-light won’t be startled by a blue light, allowing for some phenomenally close encounters and photography opportunities.


 

Fluo diving is like seeing the reef for the first time – hidden gems are produced where you would least expect them and the creatures you have always wanted to closely inspect allow you to study them closely and for longer periods.


 

The Lembeh Strait has to be one of the best locations on the planet for trying out fluo diving. The vast array and abundance of rare and unusual nocturnal critters means you have plenty of opportunities for finding ones that literally glow in the dark! Among some of our favorites are gobies which take on a completely alien appearance.


 

If you’d like to experience fluo diving while you are here at Lembeh Resort – just let us know, you won’t be disappointed and it’s a lot of fun. Try it – you will be surprised.


 

If fluo diving is not your thing, join our night dives to see some of Lembeh’s most iconic critters. The weird and wild underwater world of the Lembeh Strait doesn’t stop when the sun goes down – for many critters it’s just getting going!
