R9050 simply means Ra 90 Miniumum , R9 50 Minimum. R9 is not part of what the CRI term stands as default, which is only R1-R8
That’s a pretty nice bin you got there. I may have to splurge on a couple more. Actually, I would be in for a few extra drivers and even emitters if there are any to spare (around 5). I have a couple of Worms and Al Tools that need some love.
default low. I will get a few extra drivers.
Hey what’s the price on this and how do I get in on it? Would be a great gift for my retiring dad.
I have the Tool AAA (in Al) and it’s a very nice light.
Ordered one light.
Thanks
I'd be in for a few drivers too (but I think I mentioned that before in this thread 
)
Will send you a message.
Thanks for your support. The group buy is going on so far so good, maybe not as expected. You know, factory always requires a minimum order for all custom lights. And this GB is kinda rush for the Xmas, it only lives for about 10 days. We might have to do it quick, help is needed, any idea of other places I can post it too?
I’m in for 1.
I will be placing an order for 2 this Wednesday. Got to wait for Payday. Actually I will make it for 3 total if I’m not being too greedy. I know a couple guys who would enjoy these as gifts.
I’ll take another to help the GB along. Paypal incoming.
Paypal sent. Here’s hoping this special little light comes with a special gift box 
Sent payment for my 2 lights. Thanks!
Payment sent for one
Payment sent for 3. It’s going to be a great Christmas.
Sent a PM about jumping in on this, I’m still down for a few of em.
Payment sent for one… thx
Payment sent for 2, thinking about 2 more but might have to wait a bit.
Hi Rey, in TreviLux's review of the copper Tool preview sample, he found that the new no-pwm driver is not very efficient. It being a preview sample that Lumintop wanted response for, I assume that they may improve the efficiency of the driver before final release of the new copper Tool. How is that for the driver on this group buy light?
I’m hoping for an update too but I’m doubtful. The driver in use is likely what’s being shipped with the standard aluminum versions. It’s likely Lumintop already has a bunch of these drivers produced to use. Considering the little customization allowed from Lumintop on this GB, I have doubts they would be willing to redesign a new driver. All of this is speculation though, I hope they update the driver.
