Default 1st Build = Fail, Some advice please

Ok so i attempted to get a ps3 diode up and running using a LM317 driver.
Everything seemed to go ok with the driver build, i got all the readings i wanted to see on the DMM when testing a dummy load, yet when i wired the diode up it wouldn't light up very bright.
Now looking at the evidence i think i may have killed the diode somewhere along the line (not sure where as i wore an anti static wristband and remembered to discharge the cap before connecting the diode)i just wanted a 2nd opinion and abit of conformation i wired it up correctly.
Going order some more diode from the net tonight and will give it another go later this week.

heres some photos;

The Driver - on the bottom is 2 100R SMD Resisters going parallel from adj and v-out


Voltage of the dummy load (6 diodes and 1R SMD Resistor)


mA Reading from across the Resistor on the dummy load

Ps3 diodes are very weak......

I thought they was about 20mw, I've seen photos of them lit up and mine was nowhere near as bright. Will get some proper diodes and give them a go.
