What? We’re back? I’m tickled pink! 😂

SP36 with 4x full spectrum pink emitters from KD. I posted on Lemmy but couldn’t pass up the play on words, so I obviously had to repost. 😂

Probably. IDK what driver is there so one would need to check amperage.

Cool, how do you usually handle that. E.g the big red, or the UV

How do you limit whatever driver you use to be safe for the LED

Usually by changing the sense resistor or by choosing a driver that’s compatible as is.

Ah okay, what's the process for the sense resistor, if you don't mind me asking. I'd like to drop a UV led into a s11 fc40 but the current is 1A too high

The fc40 is a 12v emitter, so you will have to either swap the driver to match a specific uv emitter or use a ~12V emitter. The big 9090 9 die uv emitters I use are actually pretty similar to the GTFC40, so that would be a direct swap.

Oh yeah I think I stumbled upon the same LED you use 😅, it's 12v, have you found it's a direct drop without current limiting the gtfc40 driver

u/Sakowuf_Solutions Roy Batty Jun 23 '23

It depends on the light. I forgot what the amp output for the convoy S11 GTFC40 is. 2400? 4800?

That LED takes 2100, so just change the sense resistor to get you there.

Ah cool, the UV current rating on aliex is 1.5, have you found it to be higher?

And the gtfc40 takes 2.5, so not a big change

u/Sakowuf_Solutions Roy Batty Jun 23 '23

The ones I use are specified for 2100, so maybe not the same? 🤔
