    Most likely same LED then...

    Some pics of the optics section from the scanners:

    Sorry for the image quality - cellphone camera

    Maybe one of the optics-experts can give a hint?

    Time for an update

    I ordered one of these kits:

    ...And after a couple of hours of drilling and swearing (and cable-tie abuse), I have this:

    This thing is BRIGHT
    Some of the light is wasted in the optics, but the output of the scanner is a lot better now

    Had to put a fan directly on the LED-heatsink - this thing puts out LOTS of heat.

    Damn - forgot to take before pictures

    But I will rate is as twice as bright as before.

    Color temperature is the same.

    Totally worth 45 USD

    Here you go - sorry for the bad picture quality.

    Cellphone camera + moving gobos = hard to capture.

    Pictures are taken in daylight.

    Nice! I've got some Martin Roboscan 1220's that use 1200 watt HMI lamps.

    One of our new hackerspace members is big into LEDs, and just got a 9000 lumen LED module (100 watt.) I haven't seen the reflection of it running, but would love to be able to move the Martins over to something like that. Problem is that it's an array and I don't think it would really work well with the optical path of the fixture.

    I'd even be happy if I could get the HMI 1200 or MSR 1200 or whatever electronic ballasts to shed weight off of the thing. Chinese make em but they want about $400 per electronic driver for the lamp. Grrr.

    Wouldn't that be a massive downgrade?

    A 1200W HMI puts out 110000 lumens: Osram datasheet

    Yow, maybe it would be? We looked at a spec sheet and thought it looked like it would be about equal. Maybe we somehow came up wrong. It was a month or so ago.

    Maybe it was the thought that much of the light is wasted because it goes in all directions.

    Yea, come to think of it most of the comparisons of the 100 watt LEDs are versus 150 watt lights:

    Either that's a dirty fixture, a defective lamp, or not really 150W. 150W HPS lamps output 16000lm when new.

    My guess is they went around town looking for the dimmest fixture, and the fixture/lamp is probably very old. Regardless, it's not really fair to compare a new LED fixture with a old HPS fixture.
