Coach Lamp mods
Ok, here is what I am dabbling in. 
Here are 2 coach lamps. On the left is the 55W Induction. The fixture was gutted and a custom reflector built for the lid.On the right is a brand new 100W HPS.
129W for the HPS
57W for Induction.
Right now I am giving them some burn in time, before I take FC measurements.
Thoughts?

I am wondering, if it could be that light meters register different light levels simply because of the color of light.
I have read that a yellow/green color light is more efficient per candela/input watts than a blue-er light. (not stated properly, I know)
I know the frequency of light doesn't change as dramaticly as AC/DC but if the frequency of light is lower/higher, would that change how much light that a meter reads? Thinking like VD on a circuit.

Led Arrays
57W Induction
Standard 100W HPS. When the lights are on, you can clearly make out the ballast in the fixture from street level.

Cool experiment, isn't the induction suppose to have a claimed lamp life of like 100,000 hours? I wonder if it might outlast the LED.
The downside is, I make alot of my income relamping hps and mh fixtures. I love new technology but hate shooting myself in the foot.
Have you heard of LEP? Light emiting plasma, it's supposed to be better than LED. Check it out.

Yeah, I've been looking at plasma lighting. Needs perfection and time is short for that. Very short lamp life right now.
I'm guessing in 25-30yrs, fiber-optic street lighting will win out.
It is a cool experiment. Might be a market here.

Lighting sheets. I hooked up with the stamper/fabricator who makes the high reflective inserts for lay-ins. He gave me a bunch of scrap to play with.
I just called him. His company will take my ideas and enhance them. Punch them out and send them to me.

Did you place the Array at an angle for some reason ?
If you did, why and what's the angle.

I love it. There are electricians out there experimenting with LEDs. 
What driver did you use?

LED's suck to look directly at.
The light needs to be reflected so they don't hurt your eyes.
They sit at 45 degrees right now, reflected downwards, and then I made a pyramid reflector to sit on the bottom of the fixture.
So far it seems to work ok. I still have some playing to do.

Nice design. I am using some 1 watt Luxeons (lambertian pattern) for my under cabinet lighting. They work nicely, especially when we lost power for half the night (battery backup!)

48V, 12 leds in series. (2) power supplies. One for the lower array, and one for the top array.
I am hoping to incorporate a wireless dimming module in them in the future. I can shut one array off and leave one on.
This would ensure max. Energy credits and rebates from POCO and Fed programs. Still in the idea stage....
