Will replace the halogen lamps mounted in the ceiling. This LED offers a big saving in the energy budget, dividing by 5 energy needs. You will also notice that they do not heat up the cabin as much as a halogen bulb. 2,2 watt. 10-30 volt, G4 connection. Colour Rendering Index = CRI85.
Do not compare this LED with cheaper alternatives. Cheaper lamps do not have high colour rendering technique which mean that they generate a much colder light when reflected ( 90% of light you see is reflected on surface ) even if the colour temp are rated warm/white. The high colour rendering is obtained by a colour ray spectrum very close to halogen light, with more red and low blue light component ( blue light is phototoxic for children retina ). It is hard to see the differance between this LED and the original halogen bulb. Cheaper lamps also do not offer ventilation which means that the output is reduced with up to 25% already after 15 minutes of use , when at operating temperature. The electronic curcuit board is marinized to guarantee extra long lifetime in the marine environment.
