Is there a 5050 3V high CRI LED?(Rollercoster of emotions --- 3V 5050 9070 --- GT FC30 6V R9070 5050 --- GT FC60 12V R9080 7070)

So, I have some great news, some just good news(they’re not bad news, but less than I wanted) and some great future news.

Great news: All of the GT FC30s and FC60s have been produced, fabbed, and shipped. Hopefully I’ll receive them early next week for rapid testing.

Just good news: While the FC60s is easily available to be produced with a rating of Ra9080, I discovered something interesting about phosphors for smaller LEDs and why we mostly see the small die high power high color rendition stuff from larger manufacturers: they are a rarer from conventional suppliers and more expensive than larger phosphors, which explains why very few smaller manufacturers actually manufacture high power high CRI LEDs in 5050 and smaller.

I’m saying all of this to say that the GT FC30 will having a rating of Ra9070 guaranteed, not Ra9080 sadly. It’s still a very interesting LED though, so I’ll be keeping my eyes on it.

Also, since we were dealing with a sample batch, I wasn’t able to get serious any tint binning going on, which means the sample LEDs come in duvs of –0.001 to 0.003. Certainly not bad, but not what I want in the production batch :smiley:

Future great news: :smiley:

Once we get to the production batch, we will be able to ask for tint duv binning of –0.005 to 0.000, slightly rosy to perfectly neutral, and if we are willing to pay a bit extra for some samples, they will check if tint duv binning of –0.010 to –0.005 is possible, so 219B SW45K grade to slightly rosy grade.

That is valid for both the GT FC30 and GT FC60.

162

Nice!

163

Yeah, I’m actually surprised they have such tight tolerances on tint.

I’m going to make a few polls in the future on this topic, specifically the LED choice and tint, because I initially planned for the GT FC30 and FC60, but now that the mythical 3V 5050 R9070 LED is now here, I’m going to have to choose :smiley:

164

Would it be possible for Getian to make a 3500K-4000K variant? That swath of the CCT spectrum isn’t covered by their current lineup.

165

@tactical_grizzly, totally, but I never asked :smiley:

I only asked for 4000-4500k because that’s what I personally thought was best.

166

A duv of –0.005 to 0.000 would be perfect. Do you already have some price estimates for the FC30 or FC60?

167

BTW, some pictures of the LEDs :smiley:

FC30

FC60

Don’t worry too much about the luminosity measured. I’ve discussed this with my contact, and they seem to have problems with lumen measurements, as they have a similar GT FC40 sample that scores a bit more at lower power.

I’ll test the true lumen output once I get the samples home, since I now have access to a wild GT FC40 sample :smiley:

I guess it’s also time to make the 3V 5050 R9070 LED group buy :smiley:

168

3V 5050 R9070…YES!

169

Hello, what about this 18W 85CRI LEDs? Is it possible to get them?

I’m really interested in 18W 3V to replace sst40 and xhp50.2 in fet driven anduril lights.

Or what manufacture at least can produce them? Thanks.

170

I guess, but I don’t really have any incentive to get them made if they’re not at least Ra9070, or at the minimum, Ra9050.

171

The Getians are in Canada now apparently :money_mouth_face:

They should be here by Friday it seems.

172

BlueswordM, I’m in for 5 pls.

173

Well, someone seems to be a bit eager for the Getian LEDs it seems, unless you wanted to reply here:

:smiley:

174

Yes enthusiasm got the best of me. I meant for the 3V.

I’m actually content with the 6/12V hi-cri xhp50.2 I have.

175

Good news: I received the LEDs.

Bad news: I killed my Convoy M21B driver.

Any way to fix it? It now just conducts whatever it wants.

176

177

Yeah, it’s really sad.

Still, for the time that I tested it, the FC60 was pretty nice.

Good tint, excellent color(as expected), but sadly, because of the previous adventure, I won’t be able to test out its lumen output.

All of the relevant samples will be shipped tomorrow to the people who supported it me in the past.

If only there was a Canadian seller selling a working GT FC40 driver :weary:

178

Do we have any Canadians here? I’d like to offer you a deal if possible :smiley:

I need a 22mm Convoy GT-FC40 driver, and I have some extra 6V 5050 high CRI LEDs I can offer. DM me if you’re interested.

Please

179

You don’t have a bench PSU ?

180

@thefreeman, I do have one.
However, after I tested it, I wanted to put it in my M21B :smiley:

Then the reflector shorted out the driver and created a DD driver in the process.

I just want a replacement driver and I’m a bit impatient.

Then, I took the driver out to check, and nothing seemed out of the ordinary on the PCB, but it’s now just dead.
