New 3535 Hex die LED from Nichia 309/319A

Thanks for taking the pictures!

Do I see a slight spiegelei here too?

And the three pictures on the bottom are beams from a reflector or a TIR optic?

That’s the test current. That highest possible forward current is 4.8 A.

That’s exactly what Nichia should come up with. And than a flat domed version like the MZ as well.

So the 319a is green. Like, really green. :confused:

Very narrow TIR with frosted center aspheric lens, Gaggione LLC49R. Its not spiegelei (well, very subtle) in reality, it’s a very cool looking hex projection.
With normal plain TIR optics, you can see the hex projection.

What do you expect from Ra7000 6500K? It’s much much better than XPL 6200K CRI70.
:wink:

Ah, well it didn’t occur to me that those were the really cool ones. Here’s hoping the 5000K neutrals are…more neutral. :slight_smile:

Thanks for taking the time to test them for us.

Oooh, that 5000K 319a looks much better. I’m anxious to try those myself. Thanks Clemence!

The secondaries used in above tests for those curious

I agree, can’t wait for those 5000k 319A to show up.

How do they dedome ? If possible ofc, pls try that if not when you have the time, its the thing that interests many of us most :slight_smile:

Later tonight :slight_smile:
I haven’t dedoming for years. The last one was XPG R5 in 2011. Hopefully I still have the skill.

Thanks alot, if the electrical /mech dedome fail pls try chemical

Its crusial for my needs

I will buy a dozen of those on their RTM anyway yet its a good thing to know what should we expect :slight_smile:

It’s not as easy as XPG. The lens is not easily knocked off without some damage to the phosphor under my heat gun. So much different from the XPG with it’s auto dedome feature even on high temp setting hotplate.
Is slicing considered to be a dedoming? I prefer slicing though….from reliability POV

Thanks for your efforts m8, i will get 10+ pcs from those 6500k anyway but i was wondering will those be dedome freindly

We definately need some “better XPG” :sunglasses: options, especialy after the XPG nerf

I think Nichia emitters have resisted heat-dedoming for a while now, haven’t they? Isn’t slicing the dome the preferred method for 219c too?

I have sliced a for 219c’s, they do increase the intensity with minor effects on tint and output.

Interesting. Though I wonder why they don’t immediately come in 9050 rating when 219c with the same rating are already available.

It took quite a while for the Nichia 219C to come out in 9050 as well. I talked with Nichia USA about getting some of those early on and they were scheduled some 6 months out, they then cancelled, only to go ahead with them about 9 months later as I recall.
