Anyone care to explain how the bins differ? For instance, what’s the difference between the three E900 bins that are all R9080, but their prefix is sm503, sm573, sm653? Is that color temperature? I think the “e900” is indicating the output bin? No help from the data sheet. Thanks, considering ordering from Virence when I can and putting in Sofirn Sd05 6v version.
This is a new LED and still uncommon. There is not much of information available, other than the data sheet. It is just nice to see them installed in the lights.
It’s not really a thrower LED. It has larger die area than SBT90.2 and produces far less output. I think Clemence has tested that but I can’t find the results now.
Anyway E21A is not a thrower LED and this one will only throw less. But when high CRI is a requirement, there are very few choices - and this is a fair one.
ADDED:
The high CRI variant does not much more than 2000 lm at the peak. So intensity is ~3 times lower than that of Boost HX.
I used to think that “3 times lower” means y = x / 3 but “lower by 3 times” means y = x - 3 * x = 2 * x. That is the first term is multiplicative and the other additive. That’s how it works in my native language. I read your message as “3 times lower” means y = x - 3 * x = –2 * x in English. Have I used it wrong for all these years? I see you’re from the USA, so I assume you’re either native or advanced Engligh user. Is there a multiplicative term in English?
