A submersible marine lighting apparatus is provided that includes voltage up-conversion and that is configured to intensify emitted light by reducing a transmission angle of the light through one or more techniques including increasing the distance between the light emitter and an optical lens. 1. A submersible light comprising:a circular base comprising a recess for receiving a light-emitting diode (LED) array;an LED array, wherein an emitting surface of the LED array is positioned within the circular base such that the LED array is offset from a bottom surface of an optical lens;the lens disposed between the circular base and a retaining ring configured to retain a flange circumscribing an optical lens, wherein the retaining ring is bolted to the base.2. The submersible light of claim 1 , wherein the offset distance is a known offset distance.3. The submersible light of claim 2 , wherein the known offset distance is between 2 mm and 10 mm.4. The submersible light of claim 2 , wherein the known offset distance is between 10 mm and 25 mm.5. The submersible light of claim 2 , wherein a diameter of the recess defined by the circular base is between 50 mm and 150 mm claim 2 , a lumen output of the LED array is between 500 lumens and 1500 lumens claim 2 , and the known offset distance is between 5 mm and 25 mm.6. The submersible light of claim 1 , wherein the LED array is thermally coupled to the circular base.7. The submersible light of claim 1 , wherein the optical lens is a plano-convex lens.8. The submersible light of claim 1 , wherein the optical lens is a Fresnel lens.9. The submersible light of claim 1 , wherein the recess within the circular base has a sidewall height of between 5 mm and 25 mm more than a total assembled height of the LED array.10. The submersible light of claim 1 , wherein the offset is adjustable using one or more mounting elements that secure the LED array to the circular base claim 1 , wherein the one more mounting elements are configured to ...
