FYI, I opened up two of my lights to have a look at both the 219B and the 219B-V1 from the side when already mounted. And yes, I can confirm that you can differentiate the two in that way. The 219B really shows small metall areas on the sides of the cathode and anode, where the 219B-V1 does not. You have to look closely though, because it’s the place where some excess solder comes out with most of the boards.
I checked my A01 and took a crappy photo with my cellphone and an old Sipik 68 lens as a macro. It did not come out clean but it does show that the LED is a V1 219B, no exposed metal…
Yes, I did clean the dome after the pic. For some reason, me and any kind of heatsink goo have an affinity for each other… I cannot keep that stuff off of my fingers, and thus off of emitters. I use gloves on the high power stuff, this was just a quick pic and it still ended up like that… LOL
haha, I know too good what you’re talking about. I’m overly careful keeping my emitters clean, but they still manage to collect all different kinds of stuff you don’t want on them. With dedomed emitters it’s a real PITA.
Is that chips in the dome, or heat sink paste? Awful from stock like that. I cleaned my self induced messy one ip with some 90% alcohol on a Qtip. I would let Banggood know as well…
It is mechanical scratch. I tried to clean that with cotton pad and isopropyl alcohol.
I reported that to Banggood, we’ll see what will be a response.
