I would like some recomendations for a good replacement for the LED in an ARC AAA. I have 2 standard versions of these lights and one has considerably less output and a bluer tint than the other. I would like a led that is whiter and brighter. I read somewhere that NICHIA has a new led that lasts 150% longer on power consumption. Is this true. Are these brighter and whiter than the leds that came in the ARC? Also someone may know a better led to use that is not a NICHIA
