I experienced the same thing when buying from this seller. Each dome had some kind of imperfection on them. Mine were better looking than yours though. I think they are selling these off cheap because they are getting seconds from somewhere. I have found there to be no effect on the performance though.
O dang… I recently ordered 2 of them from Shenzen Great Technology…
Bubbles… Really???
I guess you get what you pay for huh?
Let’s just hope they’re as bright as the KD ones…
But, i was planning on dedoming them anyway, so that should take care of any bubbles.
Except for one minor problemo: the lowest part of all the bubbles is below the highest point of the “curve” of the leads.
There is one LED with the bubble next to the phosphor. That one I will try to shave. One other is getting a gasoline bath.
And if all goes pear shaped: the one with the tiny bubble remains in virgo intacta.
Yep. They are definitely selling seconds. When I messaged the seller they replied, “do not worry They are genuine sst-40.” So, I do think they are genuine. Very bright and very low vf! Good color as well. So, if dedoming or if you don’t mind the bubbles it’s a very good price for a very good emitter. We will have to wait for reports as to how they hold up over time though…
I picked up a pair of these in 6500k from KD. Not sure why I did it, really hate anything below 5000k. Mounted one up and tested it, very bright but just can’t handle the tint. So, now they will sit for an eternity in my LED box. Maybe someday someone will ask for a mod with that tint… Would love to see these in 5000k - 4000k.
Just got my hands on some P2/ AA binned( kit 752)(VL voltage binned) emitters from those.
In a M2x host, they start at 8.5 amps with a VTC5 battery and they hold! over 2k lumens and the incledible 370k candlas folks with the lovely pinky 5500k tint( inder M2X default glass)
A default M2X compared to this looks like a joke, literaly
