O.K. Next update I write 2 for total 4.
Let’s hope Lumintop offer 2 Led
but we still do not know.
.
the only 219C i found to be yellow are those on the KD triples. Looks more like 3500 K actually.
I’ll be in for 2 please.

Tom Tom: ToyKeeper:I would set the ceiling to the highest regulated level, and I doubt I’ll use it above that level much.
Quite. Which is also driving my strong interest in this, DEL’s driver with x1 and x7 (I think) AMC chips.
That is huge, having regulation (and efficiency) at all usable levels. Goodbye FET+1.
Plus Anduril of course.
I couldn’t care less about the FET, that’s just for headline figures for a few seconds on a torch of these dimensions, and over-powered-ness (if that’s a word).
If you like that, you might also appreciate Mike C’s approach. He has a 4-channel driver that uses banks of AMC7135’s additively to increase current up to the max level of the driver. Only a single AMC7135 chip is PWM’d so most mode levels are completely PWM free. The PWM channel is for modes below 350mA current.
Here’s one of his driver threads, if you want to check it out.
I really like what Mike C has done, but I suspect he is also a private person, like me, who doesn’t particularly like to talk about things publicly.
Look up “reticence”, for example

We don’t know yet.
Waiting for the Lumintop to tell us:
if there is only one Led,
or to be able to choose between two.
Pricing:
” Samsung LH351D NW “:LH351D | SAMSUNG LED | Samsung LED Global Website … Target $30US … including shipping?
Maybe $36US if ” Cree XP-L Hi, NW “:XLamp® XP/XT LEDs - Cree LED
Another thing to remember with tint preferences is there is such a large population of color blind people. Those who can not very well differentiate between red/ green will have a very different opinion of choices compared to handing the light to a lady with tetrachromancy and asking her opinion… and there are plenty of us somewhere in between.
Myself I like the Samsung at around 4500K.

Is the 351D available in 4500K?
Not in this Group Buy as far as I know.
I meant just in general, I’ve only ever seen 4000 and 5000K versions.
If there are 4500K for sale what’s their CRI?
I honestly have no idea.
No, Samsung doesn’t produce the LH351D in 4500K.

The list on the first page doesn’t get updated very often, but pepinfaxera’s updates are more frequent. So you probably have not been skipped.
