I’m still using Xperia V. It’s an ancient phone before the Z era. Often when I don’t have my Olympus EM5 in hand I use camera FV-5 application. Much better control than the sluggish OEM camera application. Sent you the link via Whatsapp
I finally got around to posting up the results of my output tests with the 4000k emitters, they are basically the same as the 83cri test djozz ran before but with a bit lower output naturally. I had the test setup out and figured I might as well see what they can do.
I made up a bunch of S2’s with these LED’s for Christmas gifts and they turned out great, I am also using it in my EDC now as well. With the OP S2 Reflector it is a good beam and tint but with a TIR it is simply stunning. Something about how the TIR mixes the beam just makes things look even better. This is part of why I prefer TIR’s in most lights. If I want flood then I will pull out a mixed tint triple :sunglasses:
What’s your application? What size?
I got all my Gaggiones from Supreme Components Singapore: http://supremecomponents.com/
And they’re not cheap :cry:
It goes slow!
I was again in the hospital for 2 weeks and i am now home for a bit more than a week and i am still not fully ok. Thanks for the drawings. The Aluminium Profile (should arrive next week) will be 2000x80x60x4mm. I will use only 3*144A LED´s. The Ledil JENNY-CY optic with holder is 35*50mm. I think it will look nice when it is build in the Profile.
And i have ordered a few things more (Amazon.de). A few Potentiometer to mod the driver ,so i can set min and max brightness. The Optics are in the Shopping Cart at Mouser (still adding more things to the list like driver parts and electronics that i can not get easy in germany) but have to wait till next month with ordering.
What will be the highest bin for the 219C R9050 sm57x/sm50x (i hope still it will be 280+ )
Hospital? I hope you won’t get back there anytime soon. Keep healthy man.
Is that a boost driver? Looks very similar to mine. I bought some from ebay for as low as USD 6/pc. Try to get as rugged as possible potentiometer, The cheap one usually wears faster and jumpy.
Just like me I prefer 5700K high CRI for workshop and my office.
As for the bin, I have no control of what I’ll get. Nichia always randomly decide the proportion. We were lucky I got that D240 sm403, seems like the majority will get D220 for the 3 steps.
4500K is the sweet spot for most people yet the hardest to get it right.
219C isn’t available in sm45x 9050, let alone 9080. 219B has the sw45k but isn’t very powerful and too rosy for some people. 144A is the sweet spot between power vs. package but it’s the least appealing in terms of design.
And all those high 90+ CRI Nichias also require specialized optics to mix the tint evenly. Somehow finer phosphors seems harder to mix/make. High CRI LEDs aren’t match for clean throwy optics/reflectors, at least for now. Some tint mixing either using simple diffuser or criss cross rays routing is needed.
I got excellent result with minimal lumen loss using plain Luminit LSD, the efficiency can be further improved by 14% with special request for AR coating on both sides of the LSD. Simple frosted diffusers common in flashlights didn’t do very well.
Using uncoated 5 degree plain Luminit’s LSD I got - 0,3 exposure in most tests.
