Lumin - that is very interesting about output drops with Cree’s Xlamp series leds - XPG2 and possibly XML2. You could be doing everything right with your development work, buy from another batch of U4s and suddenly lose 10% - alot of lux in extreme throwers like these - and you wouldn’t even know why. Something to watch for.

With new Cree production process you can loose more than 30%… Some of us already experienced that

Maybe you are not aware of that yet(cause you guys still have old stock emitters) but soon it will start happening to all of us.

So 160kcd of Olight and 250kcd of Maxtoch could happen sooner we expect and we’ll not be able to help ourselves… Manufacturers will stay at same throw figures of course…

Meters should not be blamed to much. Even budget ones can tell a lot about light intensity. Djozz talked a lot about that here:

Disclaimer: having said that, I feel free to make errors in what I write down here [image] . Measuring light with a luxmeter is a tricky business, as I have become to understand and as many on this forum have recognised as well. Th…
