LOC to LED?

I have recently put together a LOC in a MDXL host with a rckstr driver set to 412 ma. When I turn it on it has a fairly dim light and if I focus it to infinity, it projects a line on the wall. I am using 2 lithium rcr123. Does this mean my diode has turned into an LED or is the voltage incorrect? This diode has been sitting around while I waited for the other parts, so static could be part of the problem.

check the current going to the the diode, if it is receiving the full 412mA then it is an LED I think.

I checked the current into the driver, and its taking a full 412 ma. I guess it is a LED now. Damn I need a new LOC :(

What kind of cooling did you use? Its important to have a really good thermal connection to the host at such current levels, the aixiz module alone isnt going to cut it for a very long time.

Doesnt seem the problem here though, it started like this right from the first time you turned it on right? Perhaps your diode was damaged during extraction - those LPC sleds are a bit of a pain for harvesting... at least, i've not been able to remove the diode without sawing into its retainer on at least one side.

I was wondering about that... what about putting the sled module in a vise, and then cutting partially the side where the diode is wit a Dremel thin cutting disk, then inserting a screwdriver in the cut and prying it open?

Would the vibration of the cutting disk damage the diode? I notice that the metal used in many sleds modules is moderately soft, like aluminium, but it looks darker than aluminium. Is it pewter?

I recently tried to extract a small red diode from a DVD burner and only succeeded in utterly destroying it. Even after I broke it , I tried to pop it out, so used massive force and wasn't even able to extract it... hence my idea about using (very carefully) a Dremel tool to weaken the sled module around the diode.

I am fairly comfortable with the numerous comments about PHR803 sleds that the diode is easy to extract, so I am confident my first diode "harvest" will be a success... as soon as I get the sled I ordered.

Yeah, the phr's are the easiest to extract. The sled material is an allow of magnesium and aluminum, which makes them fun to burn
