They work as intended.. got quite a few of these RGB modules over the last decade They perform around their specs. and most will accept PWM/TTL modulation and the more expensive also analog mod.. Got them from around 300mW up to 17W and some are wide-beam.. - alignment on a cheap 300mW...

That would be something if OpticsLD literally is doctrinizing/rigging datasheets for sale purposes. Curious about where that "Typ 2.0" comes from on OpticsLD listed eBay-datasheet, that also tempted OP. If you look at the datasheet source-code (highlighted in RED, upright) as far as I can tell...

What lasermeter are your getting 17W on the so-called 15W Blue demon unit?? When I asked, I was told from one of the distributors I been working with, the dual green was between 2.6 to 3W and blue 10 to 12.5W. It's a dual-diode setup and the diodes ain't tortured for obvious reasons, as its a...

Yep, Im familiar with datasheets, it was more since you referred to the fact on possible NDG7H75 gain, and if the eBay datasheet you where highlighting could be trusted. And I could see it was an OpticsLD listing, that posted tolerances that didn't match any of my datasheets for the NDG7H75 or...

Wicked, thx for posting.. love the beam shots on the table.. Also had a NUMB12 in transit, though looked nothing like yours when it arrived, more like a Chinese AA battery. Seems farbe2 was spot on, hence dual emitter for the red. How much did you end up paying for one of these micro RGB NUMB12...

As mentioned, you usually have some wiggle-room in some hosts. I don't know how the Sanwu Spiker is build, and what amount of thread you have around either the pill or the tail-cap that you can align to cater for battery length. Had a 1.6w 524.2nm in a spring-fitted host with no dedicated...

You can find the most common cells here. https://lygte-info.dk/info/indexBatteriesAndChargers UK.html Its a Danish site but all test for the last decade are in English. You choose the battery segment on top, and then you can go to a given review of that cell or use the comparator to stack...

They clearly want you to build something with that front-selection...[angry baby, baseball bats, knives, alarm whistles, and high-powered lasers] Please do so.. build it..!

Looks like standard off-the-shelf 300 series cheap Chinese laser pointers, just rebranded with a Sanwu label. If you get them from Amazon, AliExpr. eBay, or Sanwu. I doubt the inner hardware differs, only the amount of mock-up, but I haven't been there for many years, so I don't know if its...

That is the exact same question my girl asked and I had no idea as I was so gobsmacked / puzzled to see that single chinese AA-battery in the package looking back at me, that I didn't want anything to do with it. I have checked the battery... yes 1.56V ;) (Winner winner chicken dinner...

Our NUMB12 parcel from OpticsLD arrived today purchased at the start of February on Aliexpress.. "NICHIA NUMB12 465nm 8.3W 525nm 4.8W 643nm 10W" that to my surprise was shipped. But it looks weird..I haven't seen a NUMB12 in person, but I got a bad vibe that this ain't it. Looks a lot like a...

It's around the price I also got from sources in China. 250 to 400USD I purchased one in early February, though not from eBay but from one of the links I quoted in #5255 where the prices were even lower that those early eBay prices, though same seller And I didn't cancel it, even though it...

The main top-video (at Sun.co.uk) seems to be a mix of two different situations, as midway through the video, they have inserted old footage from protesters in Chile where an unmanned police drone was targeted and brought down, and Sun now tries to push this 5-year-old footage as it's the plane...

Though, this UK 99p seller did come true, so he do honor eBay listings that goes way under MSRP. (1/3) It arrived today from England (looks brand-new, as it should). https://www.ebay.com/itm/176256838856 Sofar only tested with a 488nm handheld stubby 1x18350 from around 2017 ...

Arrived today, so this UK seller seems solid. Were unsure if her would honor the auction price One thing is to purchase these RGB diodes from OpticsLD on Ali, its another matter to actually get him to ship your order.. Still have an order since start of feb at that specific seller (NUMB12) Its...

Wicked experience, but also on the verge that you could be hanging & dangling with so much patience if it is a purchase back from around September, but it likely varies from region to region, and payment method, and what amount of safety-net you have.. Have you checked the accuracy of these BT...

You can wick a compound with copper metal powder. that will set and do somewhat okay with heat transfer (all things considered) - if you absolutely have to meet certain size-offset tolerances but it will be a messy job to align etc. - but it sounds like it's just a standard off-the-shelf 9mm...

50 bucks.. that's quite a bit lower than the inner market value for these +20W self-contained mashup LPMs on Chinese marketplaces like Taobao & Alibaba/Aliexpress & eBay where they are usually around the 150 to 200 mark, though USD. https://www.ebay.com/itm/176256838856

Roger that.. I get no results on eBay, but there are a few listings on Aliexpress, Alibaba, Taobao etc.. Also from the same vendor, as the one that cancelled your eBay purchase. though to a way higher price now, and why I speculate, the reason for your cancelling of your order, was more likely...
