it sounds like you want full bronze lights with a single hole which is a good option, but you want to pay for the price of a composite or plastic light. your right that majority of LEDs are cheap. however, UW light manufacturers use "binning" (selecting the brightest and highest quality of LEDs that are manufactured) thats a little more pricey. the majority of the cost isnt even the LED itself...they have to take a big chunk of bronze and have a CNC machine billet it down to a single fixture, then you have someone assemble it with the LEDS, Tritonium lens, water tight deutz connections, driver, etc... THEN (most importantly) you have to warranty that product for 1-2 years and cough up a brand new light or driver god for bid it fails. that is going to be an expensive light. and completely justifiable IMO. and by the way the mark up on UW lights is lower than any other marine product (at least that i've ever sold) not sure why the plastic under the water line bothers you, but your best option (based on your attitude towards the price) is likely going to be amphibians or Scarab Chris' Lights.
