And off of that… If there is an improvement to lumen density, then it’s a better thrower. An increase in die size couldn’t hurt anything, so it becomes a non-issue.
I compared dimensions of both the XP-G2 and XP-G3 from cree data sheets and their dimensions are identical. However, die size itself is not mentioned anywhere.
Because 3rd generation sounds better than new led which has slightly bigger chip and same of even slightly worse lm/W/mm^2 performance compared to 2nd generation (XP-G2).
Somehow, I doubt they’d go to the trouble of releasing a product that had nothing new/better to offer to the world. They do plan on selling these, right? Their existing XP-G2 customers are the target audience, hence the naming convention. If it weren’t an improvement to XP-G2, they would be stupid to call it XP-G3, since those customers will presumably be smart enough to read the datasheets of the two and compare the specs. before spending the money to upgrade.
Well, i was kinda soft about that matter Its designed for general lighting areas mostly, yet i am pretty confident there will be XPG3 thrower edition soon enough
Or as an Arrow manager mailed yesterday: there are rumors for for improoved XPE3( bigger core, better bond wires) Unfortunately he is a CPF member( whitch ofc is already a huge sin in my eyes :smiling_imp: )
Another 3.45mm LED. I really don't get it. Is there really a cost saving for them to reduce the die of the XP-L to this size? I was holding thumbs for a Cree 5W High Intensity. Anyone else seen this gap?
Hannes - you probably won't get a response here. We generally don't pay attention to watt ratings, because (I think) that's based on CREE's specs for max amps, of which, we totally dis-regard. 1.5A or 3A max ratings are pretty meaningless. We take 1.5A LED's to 4-5A regularly, and 3A to 6A+ even.
If I were building general lighting products though, it would be an important consideration for sure, for both lifetime and heat issues.
yes you are right. When you only have 1 or 2 leds to worry about you will not be bothered if it is burned out due to overdriving it after a few months. But when you have to worry about +1000 driving it harder makes no sense. For me it is about the PCB foot print to Die size ratio. With the XP-L bring a XM-L on a XP foot print there is really a need for an XB (2.45x2.45) led with an XP-G die. But it see that cree is not really interested in that market.
