Did you find another source around the same price? Does anybody have an RGB NUMB12 in transit atm? (shipped) if so from where /link? When I looked into these arrays before the Lunar New Year, the prices were quite a bit higher, than the listed 114USD on eBay.. all the other sources I could find...

sure, you can get green above 1W..but you will lose some in the beam-combining optics. The channels I talked with in China refer to them (green) as 1.65W x2 but these dual diode handhelds are still pretty new. The feedback I got from a week or two ago. Many sellers circumvent the wording of...

Many of the sellers on Aliexpress are just customers in somebodies else shop, often flipping / dropshipping items, and can at times explain why they are quite clueless about what is actually happening. but it obviously varies from product segment to segment. My biggest problem with Aliexpress is...

Will test with numerous well-known diodes and different wavelengths and try to have the voltage and ampere present while doing it, as that will give a good indication if they perform somewhat loyal and in the ballpark where one would expect, - at the end of the day, I did not pay a lot, ao my...

LPM Test with some old labby's from China 2015/2016 - 55USD# incl delivery to Denmark from the Chinese wholesaler Banggood (# on sale). They were both labeled & sold as 2500mW units and it was the same listing i got both from, though with 4 months difference in purchases. Looks identical from...

Purchased these two budget LPMs in early 2018' and now had them for more than 3 years, and thought I would share how they stack up and show the damage to the sensor area, after numerous years of use' - as I did also took some pictures while they were quite new and been lazing them with all the...

Sorry to rewake this old fellow of an LPM review, but sadly not much "review" as the title claims over the above post.. more like "see here is a picture of a Chinese LPM, and I'm not turning it on and won't share any info on how it performs" So I will try to dig a little deeper and hopefully...

Give him a deadline, and write it here PM and on the email that is on the PayPal recipe' and tell him if you don't hear back in like 10 days from now, you will conclude from the lack of response, that the purchase is no longer in play' and he is simply not able to deliver according to the...

They sadly do as many chinese vendors do, dance on a fine line between BS, confusion & deception, and then what have an ounce of truth to it. so 20W is 20W from the wall outlet and same with the 30W and the 40W. (and even here its doesn't match with the wall outlet that was quite a bit lower)...

Vice versa,, hence your edit. but let us move forward.. you're not a mod your a pretty new member here with a tad over ½ year, I'm not a mod and not that active, and I would not start to moderate other users on forum etiquette where certain things are frown upon, even though it varies from forum...

nahh move on and please refer to topic.. all this other crap, with insults... no thx.. - and the only one who needs to chill.. are you....(check yourself) and this mod-attitude... you even mod licking in your sign. (wow) if you have any insight into these LPMs or even had one... please share...

Same here.. also been looking at the Sanwu.. but it is still like 350USD and likely even more after shipping and tax, though I reckon I could likley try Brainiac75 ones out... and compare it. In the blue wavelength.. I have so far been very impressed with both units.. and the 488NM stubby was...

C'mon..It's the two main LPMs threads for those exact units (you do get that) one refers to the Tornado and the other is the Pocket. and the text refers to both units and compares their differences & results and highlights certain questions and confusions in both threads. - no reason to...

Sorry to necrobump this old fellow, but seems there is a lot of speculation, some more details as this looks to be the main thread of this Tornado unit.. Been having these units now for multiple years, so about time, I put in my view.. It was what I needed hence my limited need & purse.. aka...

Sorry to necrobump this old fellow, but seems there is a lot of speculation. Been having these units now for multiple years, so about time, I put in my view.. It was what I needed hence my limited need & purse.. aka very cheap LPM for measuring my portfolio of NUBMs..05.06.07.08.. Lazing...

Mehh' already highlighted in post #20 from a few weeks ago with numerous links to each relevant segment. - and for people using lab-gear, like DMM, electronic loads, bench PSU or scopes and likewise, the danish user behind Lygteinfo with the forum-name HKJ on EEVblog (and other electronic...

Yes, the 40W is a dual diode setup, though they are not too happy by informing which LDs are in the array, my guess its Nichia A0. NEJEs high-end lineup with 20w and 30w should be the A0 on my testing. and I doubt that you will get anywhere close to the rated 15 optical wattage,, my guess is...

Heres a "down the barrel" picture of the 20w variant./that thin long labby with a PWM controller and display that useally are being sold with the Neje Master 2 as I recall. I recall Neje claimed it should be an A0 LD, natively

Thx Cyparagon for your input. I been fooling around with it, here yesterday, and so far haven't blown anything up, that's always a good start, I Am left with the impression that It's preferred to have one PSU in CV and the other in CC when doing parallel, as a general preference. but in my...

Just a helpful link for people looking into Li-ion batteries and wondering which high current INR/IMR model to get and how they stack up against other brands-performance. I often use this danish site where there are no-nonsense or secondary motives. (just a lot of good info and testing) Many...
