As Cobalt mentioned, it looks to be a fake. The die is to small to be a Cree XM-L. Also yours looks to be another variation, as the substrate around the dome seems to be close to bare green (except for the two squares in the corner) and that one looks to have round bond-wire pads. it looks to be another new latticebright variation of that LED, or even another unknown counterfeit copy manufacturer has surfaced.
No it is easier, the die is smaller. I could spot the fakes without having to remove the reflectors on a new light recently. Some need to be inspected close by but this breed of fake xmls is almost too easy.
And yeah got refunded but hated it this time, really looking forward to this light.
- Look closely, the Latticebright factory/head office is as fake as their products. all the trees but one are copy-pasted identical, the grass is poorly photoshopped, birds photoshopped in, fake sky, rendered asphalt, and fake LB Sun. :sunglasses:
It is such a shame though
I have a few LB LEDs with real nice tint, Maukka tested one AMD it had a real high CRI
So sad they are not just making the nice tinted and be proud of them, same light same price 1 with XML white and 1 with nice tinted LB advertised honest, I would get the LB.
OT: But the windows are opened different and the reflection of the surrounding seems to be real. Perhaps its not very nice around the factory and they wouldnt show it.
Photoshop and LB doesnt match. I would think its a Photoshop-Clone or Copy.
“But the real question remains. How good or how bad are these lookalike LED’s really?
We set out to compare some of the clone LED’s to their original counterparts.
To simplify things we were interested to know how well these LED’s convert electrical power to light, this is called Luminous efficacy. Considering temperature is the Achilles heel for LED’s, we would also like to know how the Luminous efficacy effected over a range of temperatures. Notoriously cheap lights does not have good heat conductivity, and that is where you will find Lattice Bright LED’s.
First thing we did was to order two Lattice Bright XML2 LED’s. The T6 bin was the best the agent could provide. We also asked for natural white (5000-5500K). After they confirmed the sample order we also asked for the same from our Cree agent, Cree XM-L2 T6 5000k. A few weeks later we got the samples.
The setup is simple: Using a custom built Isometric sphere we compared the Lattice Bright XML2 output intensity and measured the temperature of the star and the power(Voltage and Current) that was applied. We did the same with the Cree XM-L2 T6 5000k…….” Read the rest here.
Aside — re canines, bicycles, and traffic — you might add some of these reflectors for headlights — these are far brighter than most (made to a European safety standard)
These are ‘corner reflector’ design that throw light straight back toward its origin, so light up like crazy to cars in traffic, no matter how they are bouncing around on you or your bet or bike.
We’ve used a lot of them and passed them around to family.
man this thread is terrifying! Now gonna go buy a magnifying glass to go over ALL my 50+ lights especially my Coasts! Anybody know what LED is in the new 200 lumen Mag XL50 by any chance?
they can copy everything but performance.
time to set up a kickstarter for an all in one integrating sphere,spectrometer,and cri measurement device that the average hobbyist can afford.
Thank you all again. I was pretty sure it was too small for a XM-L, but I needed a second opinion. This is from the replacement light that Fasttech ASSURED me was authentic. The LEDs are different from the first one, but still not the ones they advertised the first time, or told me that they had confirmed authentic this time.
They took my money Feb 06. I’m double plus pissed now.
