From this picture most guys may conclude quite opposite
New XP-G2 S4 2B right (orange) is “Angry Hulk” S4 LED when de domed. Orange as a freaking orange and yet green as an Angry Hulk when de domed… Fascinating transformation… Just like Hulk in strip or movies…
Real and old king XP-G2 S4 2B is the one on the left.
I hope Djozz or anyone else can take de domed aspheric beam comparison of both.
I recieved few of the new die xp-g2 s4’s and instaled one in a B158 just to test the amps, turns out this thing pulls 4.5A with 30Q @ 4.17v. Im to lazy to dedome it now but with dome on my lux metter says 122kcd at 1m… I guess this thing wont hit more than 200kcd dedomed… huge dissapoitment.
Need to find good source for few s2 2b leds, i want to push my b158 to 290kcd again.
I just said that it “looks like” has a larger die size…
With the current knowledge that the latest XP-G2’s seem to have larger die sizes (your own findings ), and claim similar increases in Lumen/Watt, plus the wider viewing angle of the G3 (which admittedly might be a dome change) and the lower resistance and forward voltage, I would say current evidence suggests that they “look like” they will have larger die size…
We wont know for sure till we get some… And I intend to get some, just in case they are great…
Dont throw too much hope in this m8, dont you see it has a XPE desing? The whole top is covered with a phosphorus: this automaticly means a bigger emitting angle, its clearly desinged for general lighting . Yet, we have to test it ofc…could be good enough
We all seen what they made from good old XP-G2 emitters (not just mentioned S4 2b from this thread, they messed them up in all bins) so can we expect something good from XP-G3?
Probably not…
I always thought that emitter throw performance should be improved in future by creation of new an innovative led emitters but the new trend is to make bigger phosphor layer emitters which will pump more lumens out of a dice… Pushing lumens and ignore lux performance?
Pushing lumens instead of lux? Maybe someone here may like it. But I am not one of them…
Ordered all S3 bins from Mouser lately( K51, KE51, K51 and K53), they all came “improoved” ones…… definately not good for us:/
It would be great if an australian guy order some emitters from Cutter for evaluation, if they came out good we could arrange a group buy, at least the EU folks arround here, personaly i would buy at least 100 if they came one non improoved
About the S4 issue: Arrow Eurpoe has 5 bins S4 in stock( reets of 500pcs) - the problem is they dont offer samples from then, i cant even test …. one cant tell whats inside only from the part number( the production dates are 05-07 21015)
