● “Elude” Eco-Friendly Barnacle-Resistant Coating - We coat all SF model HydroGlow
Underwater Lights with Elude, a revolutionary eco-friendly (biocide-free) marine
coating that has effectively tripled the barnacle-free operational time of our lights.
● “Impervia” No-Porosity Marine Epoxy Resin - We use Impervia, a state-of-the-art
marine epoxy resin, to construct our lights. Other resins retain some level of porosity
which can allow micro-droplets of brine to penetrate, potentially resulting in corrosion
or light failure. It also has a higher flexural strength rating. And, unlike polyester,
Impervia is very resilient and less prone to shrinkage or warping, meaning it can
withstand an extreme range of water temps from a summer ocean to under the ice in
the winter. Finally, we flood all seals and critical electrical components with Impervia to
ensure protection from corrosion and sea spray. Cheaper lights will coat only the seals
(and with less effective materials).
