Here is some community data that should be pretty accurate, as an alternative to trying to read the tiny relative output graph from the Nichia datasheet:
Rather than just settle for the closest reported current, I did the math to interpolate and got 605 lumens per emitter. You also have to consider losses from the optics. I don’t know what optic the D18 is using, but a Carclo 10mm TIR is supposed to be 92% efficient with similar sized LED’s, so that makes it 557 lumens per emitter.
That would suggest right at 10,000 lumens, if it really is able to pass 48A at turn on.
That makes perfect sense iamlucky13. That would line up exactly with why Hank said 10,000 Lumen. He obviously knows to account for those things too, unlike me. But I understand this a bit more now. Sure almost 11,000 technically, but impossible for the light to actually put that out.
Reminds me of the the difference between what horsepower a car is rated for vs what horsepower the car can actually put out at the wheels. Thanks.
This is actually an item returned to the shipping company’s operation center, not a really “warehouse”.
For the US shipping, I kindly ask the customers from the US to make sure the shipping address is correct/valid,
even the zip code is very important, if the shipping address is invalid/incorrect, the package will be
returned to the sorting center, and will be DESTROYED there, there is no way that the package will be
returned to us, or reshipped to the customers. Please spread the words.
I also just wanted to mention that there is a great group of people over on Reddit dedicated to the enthusiasm Emisar and noctigon products. They invited me to join a couple weeks ago and it's a fun place to talk among like-minded enthusiasts! Here's a link https://www.reddit.com/r/Hanklights/
Thanks. I’m surprised I didn’t knock any Koala’s out of trees with all those lumens.
I’ve also now found a compatible diffuser for the DT8 - the 22-50mm diffuser from Kaidomain, so have updated my review.
