Hopefully it’s ok to ask here, but I’ve got a QT-L on the way and I was wondering which of these emitters would work without frying. Thanks everyone!
SST-20 Deep Red
Nichia 519a dedomed
Edit: it appears from recent comments the 519a works
Thank you, much appreciated. I’ve been a fan of flashlights for a good while, but I’m just finally figuring out how some of the stuff works. Embarrassingly, I didn’t think about using the battery to limit power. Oops!E17A is max 700mA
SST-20 Deep Red is max 2000mA. S
real-world use tends to be higher, but the hotter it gets the shorter the life is. There are no exceptions to that. Heat kills LEDs.
I'm assuming the QTC current is only limited by what the battery drain is...I'm not sure the technology. I'd email them.
I don't think the light has a driver.
May I ask where you bought the dedomed 519A?My tracking says Friday. I just ordered a few dedomed 519a in different CCTs to try out. 5700, 4500, 2700. Hank said their 16mm board isn’t compatible with the E17A so I’m hoping the DD 2700k fills the void.
Edit: does anyone have battery recommendations that are safe for the QT-L with 519a? I’ve got Samsung 30Q and Sanyo NCR18650GA here.
From Hank Wang at Emissar/Noctigon. I emailed him and he asked me to order whatever number of this linked item I wanted and then email him my order number with what emitters I wanted and he would “ship according,” as always. Great service from Hank! He has domed and dedomed, but not sure if he has 4K or 5k. He sometimes has stuff that isn’t listed, but I didn’t ask this time. These are red boards, I would think white boards might be a bit better for tint, but I’m familiar with Hank so that’s where I went. I’d really like to learn to solder my own, but I’m just starting to learn how all this stuff works.May I ask where you bought the dedomed 519A?
I bet it’s already there and they just need to scan it still. I know these sorts of scans have been taking longer for me as the years go by. I’ve even had packages not get scanned until a few facilities down the way lately. Fingers crossed!Well dern, still label created here.
