Anybody get/use one of Cutter’s 4000K 83CRI D280 219C’s on a 20mm notigon yet (here?) Curious if it’s really a D280 like Djozz’s 5000K one was. Seems like a good deal if shipping doesn’t kill ya.
Well from where I’m sitting, it looks like ordering 30 of them gets free shipping to the USA, and with the BLF discount works out to $91.16 USD or $3.04/each at the present AUD to USD conversion. That sounds like it’s screaming for a group buy, yeah?
edit: AUD to USD conversion already slipped more, so it keeps getting cheaper…
You know, for those in the USA I’m not sure a group buy even makes sense really. The Australian Post shipping option to Colorado from Cutter is only $14.10 AUD which works out to $9.92 USD. Given that a priority flat rate envelope is $5.75 USD does it even make sense to try a group buy? If you get 10, that means they’re $4.03 USD/each shipped, and if you get 3 they’re $6.34 USD/each shipped. That’s really not bad at all.
I’ll have bare 5000k 219C’s available soon(this week hopefully). I’ll be able to ship them in the USA for about $5 each. I’ll have about 40-50 available.
Yeah, you’ve got to click on that and select “Compare rates: Australia Post” instead, and remember that what you’re seeing dollar figure wise is in AUD not USD. There’s a small handling charge too (AUD dollar or two), and PayPal or your credit card may charge you a small fee for converting currencies. Just keep all that in mind.
Hell welight, I don’t know what else you could do to get people to buy those, it’s a screaming deal (particularly if you’re in the USA) buy it only looks like three after me have been sold?? It’s not like we can get those 4000k 83CRI D280 ones anywhere else…
Appreciate your support. My comment was a general one in that most people trying to buy stuff from us have a MAJOR issue with our freight cost. it was just nice to see it explained that while we are not free shipping like the chinese vendors, we are not over the top expensive if you choose the right ship option
Here’s a beamshot comparing the dedomed Nichia NVSW219C @ 5.7A vs a dedomed XP-G2 S4 2B running direct drive. Both are focused for highest lux in 1504’s. I got a reading of 326kcd from the dedomed Nichia vs 463kcd for the XP-G2. The colors are fairly accurate. The Nichia is on the left.
It feels like there’s more to be had out of this LED, perhaps more dedoming attempts are due.
You have been busy! Nice work and comparison. The result looks suspiciously close to my sliced result of post #106: good tint shift but not the expected increase of die luminosity.
I'm not sure what's to blame. Could indeed be dedoming quality, but it may be caused by a difference between the Nichia and Cree phosfor recepies as well: the photon recycling causes a different spectrum that is more towards red and is thus measured lower. Or the Nichia phosfor mixture is saturated at a lower light intensity. What really happens in the different dies is easily beyond my expertise and may actually be extremely complicated
Let's hope it's just dedome quality and a succesful method pops up soon :-)
