Not picking at your methods or anything, but why not just run it at its rated current? Then there's no question what power it can reach. You also get to see if there's any anomalies in the wavelength when it shifts, if it shifts etc. I noticed with some diodes when you run them at threshold...

What does that tell you about that one diode that reads the highest at threshold? I have not tried this approach. Typically I go by which diode it is and if there's a data sheet available I set my current limit to its maximum rated current and mark down what output they all have at that...

That is really odd, I've taken apart a130s and a140s, the only time I've seen a marked up phosphor wheel was when the inside of the machine was really dirty. I've gone through several a140s and the only thing I noticed was at the diodes start to burn out after 10,000 hours or so. The red LED...

How would that make a difference? The phosphor wheel produces green and a lighter shade of green almost a yellow. Then there is a dichroic filter on a wheel that produces the reds but only one of those. To my understanding there's only two phosphor Wheels in this machine because it employs a...

Well the interesting part about this projector is the use of dichroic mirrors as opposed to the silver first surface mirrors seen in all the projectors that I've opened. They are used everywhere where the beams needs to be steered. The other interesting thing is that there are two light boxes...

One of my kids pointed it out when watching a Lego movie. The other likes the the contrast and brightness when using it for tinkercad. Though he's expressed more interest in taking a 🪛 to it 😆

I watched a few movies on this machine and I'm not very impressed with the image quality. Too many anomalies in the picture when running HD films during scenes where a lot of motion is involved. They also use a phosphor wheel as opposed to a red LED similar to the BenQ projector with the...

Found it through Google search. "This is in agreement with what DTR and other members said earlier that the less efficient LDs usually have higher wavelengths." https://laserpointerforums.com/threads/test-of-diodes-in-nubm08-block-one-by-one.102804/ So this is the 08 block that I was testing...

I was referring to a scenario where say a block of diodes when tested individually at a given current the lowest efficiency diode in that batch would present a higher wavelength than the others in that same batch. I'm going to have another look with the search, or perhaps I'll try it out on...

Haven't begun the harvest yet. I set it up to use for a few movie nights. First time using a projector with more than 3,000 lumens 😲

Got a question for you folks. I can't find any information on it but I do recall reading somewhere that the lower efficiency blue diodes tend to have higher wavelengths. Now in relation to the nubm 08, is this true and what properties do the higher efficiency diodes present, if any difference...

Sure, no problem. BTW Is there a private message option on the forum? The only thing I'm seeing looks like a public message board, or am I missing something?

Any specific sections or parts?

So the 08 blocks were around back then? I thought they were more recent. I'm dying to tear this thing down, it's got a liquid cooling system in it as well. Original price tag for this unit was around $12k USD, picked it up for $350 and it's in mint condition with low hours. If it's 08s that...

Anybody know, or can throw an educated guess as to what diodes (which come in the Gold blocks we see the nubm 44s) that would have been used in early machines back in 2015 - 2016? I picked up a near 7,000 lumen unit with less than a thousand hours that contains eight of these blocks. I'm...

Unless you took a direct hit to the eyes, or were trying to burn objects up close and staring at the spot, there is not much to worry about.

I missed that one, what restrictions were imposed in the USA? TBH I didn't expect that one. Was there any major incidents that brought this about?

Any idea what current would be a safe upper limit? I had not seen much info on these ones being sensitive. Were you using a led driver or something more suited to LDs?

I wasn't sure if I had missed any discoveries with this diode. Pretty much all the comments and threads in the search are from around the year I bought them. I have "2A" written on the baggie it was stored in, so i guess I'll keep it in that zone. Thanks for the replies, Gents.
