We would like to try to dive with ultraviolet light to see if our cold Nordic waters have plants and animals that have bioluminescence.

The torches on the market are quite costly. Instead, we thought to buy a torch / host with 501/502 module and just switch the module/ led to test. Ideally, we would like to use a better body than the simple, yellow kinalamps.

Anyone who has suggestions for a good torch / host for the 501/502 module?

Thanks in advance!
