Note that some municipalities have discovered a downside to LED lighting: Because they waste less energy in heat, LED traffic lights are at greater risk of being obscured by snow and ice. Rumor has it that some have started including thermostatically-controlled heaters, to counteract that.

I doubt anyone here actually knows the best you'd get would be someone researching it for you.
Look for technical details on these things and see what you can find-out.

lumens/Watt should be a good place to start.
