The Synergy3 is o-ring sealed at the lens, where the sections come together and at the retention nut. The retention nut must be tight! With careful assembly and proper o-ring maintenance we have had no leaks in our own testing. That said we are not able to test at any depth past 8 feet deep and the Synergy3 was not designed to be used when diving.

If the light is fully submerged the button cavity may fill with water. That is OK, the seal is further back, you can shake the light to get most of it out and it will dry by itself.

The Synergy3 uses standard AAA, Ni-MH rechargeable AAA or 10440 Li-Ion batteries. Please use caution with 10440, they should be unprotected, button top cells purchased from a reputable supplier.

The Synergy2 and 2.5 are o-ring sealed at the lens, where the sections come together and at the retention nut. With careful assembly and proper o-ring maintenance we have had no leaks in our own testing. That said we are not able to test at any depth past 8 feet deep and the Synergy2 and 2.5 were not designed to be used when diving.

If the light is fully submerged the button cavity may fill with water. That is OK, the seal is further back, you can shake the light to get most of it out and it will dry by itself.

The Synergy2 and 2.5 use standard AA, Ni-MH rechargeable AA or 14500 Li-Ion batteries. Please use caution with 14500, they should be unprotected, button top cells purchased from a reputable supplier.

Synergy1 and 1.5 are o-ring sealed at the lens and where the sections come together. With careful assembly and proper o-ring maintenance we have had no leaks in our own testing. That said we are not able to test at any depth past a few feet and the Synergy1 and 1.5 were not designed to be used when diving.

The Synergy1 and Synergy1.5 use standard AAA or Ni-MH rechargeable batteries (1.5v and under). Higher voltage batteries will fry the driver.

Due to the custom nature of Frelux products as well as the fact they are made by a single person start to finish pre-orders are a necessity. I limit them to what I think I can produce in an acceptable time, usually shipping within 4-6 weeks of your order.

When I started this venture I had chosen Freedom Lighting as the name. Well someone was asleep at the keyboard and neglected to find another company on the east coast with the same name. I then decided on FreeLux instead but wouldn’t you know some sneaky domain hoarder wanted $10k for the domain so we decided heck with it lets follow the example of many before us and make something up! We dropped an E and Frelux [free luhks] was born.
