More context about the new Getian LEDs:
https://budgetlightforum.com/node/81315

As for why: 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 between the FC30 and FC60.

I’m personally biaised to the FC30 since it could be used as an alternative to the Nichia B35AM with much more versatility because of the choice in MCPCBs, and higher power handling.

The FC60 would mainly be used as a higher power version of the FC40, and with guaranteed tint in the final production batch.

That is a tough choice. I would need both but I voted for the FC30 because it could be used as a replacement for the XHP50.3 90CRI.

Do you need to purchase a certain number of leds of the final production batch? Maybe if this group buy is successful we could start another one for the FC60 later.

Would the FC60 be only 12V or also 6V? With 6V it would be better than the FC40 because there are more drivers and it can be used with 2S battery configuration.

Anyway, I appreciate your effort to bring more high power R9080 leds to BLF.

Yes, I need to purchase a certain amount of LEDs for the final production batch if I want to be able to get lower prices(obviously) and guaranteed tint binning.

The GT-FC30 and GT-FC60 can be 6/12V depending on the MCPCB in the final production, which is another reason to pick them over the currently available FC40.

While I’m excited at the prospect of either, I have several XHP70.2 lights that don’t see use because I don’t like the XHP70.2. I will definitely buy 6V GT FC60s.

So FC60 can drop into any XHP70 boards and FC30 can drop into any XHP50 boards?

Yes. That’s the stated goal.

Otherwise, we’d have the same problem the GT-FC40 currently faces: 12V only.

It’s a limitation that I don’t like and plan to solve, since it would make the LEDs themselves a lot more usable.

Aaah I don’t like this.

I wanted the FC30 to be more popular lmao.

Well, once I receive and test the LEDs on Friday, I’ll close the poll.

Good one, but I can see why people would want the FC60: more efficient FC40, with our own tint binning, and 6/12V compatibility.

Also, I think this is the main reason why:

FC60 = R9080.
FC30 = R9070.

Now you see why Cool

Still…don’t listen to them.

FC30 is 2steps ahead of any XHP50.3 and folks are using it in big numbers. 
Do you guys even realize form factor we are talking about?

I think people are choosing the GT-FC60 because with 6V it would be a direct swap for the XHP70.2. Also, most XHP70.2 with 90CRI are slightly green and the R9 is not very high. If the GT-FC60 really comes with a negative Duv and a better efficiency than the GT-FC40 it will be my new favourite 7070 led.

I would have a few flashlights for a GT-FC60 in 6V. 6V drivers are more common than 12V drivers.

For example, I have a reflector for eight XHP70 and with the GT-FC60 in 6V I can use it instead of the XHP70.2 and get a beautiful tint. Cool

Maybe if the two future group buys are successful and BlueSwordM has time later we could also run a group buy for the GT-FC30?

Perhaps.

I’ll leave the poll running, but it’s pretty obvious which LED will win Silly

I’ll do it with the FC60 unless the tide is massively reversed.

It’s still a fine choice, but it looks like I’ll need to sell some lights so I can afford getting 7070 lights Silly

All of the stats are in the original thread:
https://budgetlightforum.com/node/81315

Color, tint and throw numbers are all known, but lumen numbers are the thing we don’t know much about yet.

I’ve got to decided until I make the order, but looks like we’re going with the FC60 after all Cool

I mean, it’s fine, I can perfectly understand wanting the R9080 FC60 over the R9070 FC30: the improved dynamic range offered by such an LED is considerable.

However, my envy for the FC30 is still greater, so I’ll open the GB a bit later than I wanted so we can finally decide(after the samples are tested obviously).

That’s my reason. I have several 6V XHP70 lights sitting unused because pretty much all forms of the XHP70 are ugly.

I’d also buy FC30s.

You know what, F it.

The XHP70.3 HI doesn’t look very good, so we’ll go with this one instead.

After that goes the FC30 Big Smile

It has been chosen.

The GT-FC60 will be the 1st LED to get a group buy.

Let’s see how they perform first, the poll is a bit hasty in my opinion.
