Intl-outdoor's 3535-size 365nm UV-led on 16mm Noctigon (Royalighting RY-3535P)

Thanks for the info! I especially liked the monochromator test. :slight_smile:

Thanks djozz. I was waiting for you to test this.

I put one in a quick p60 build and at 700ma it’s doing great. Here’s a Canadian 5 dollar bill. (old one)

This is in my kitchen on a blue table with the ambient lights on. From what I understand this bill only lights up in the 365nm wavelength. (I’m sure there’s some variance)

Thanks again for your test.

thanks for the test , i believe 1.5Amps will be fine on copper for longterm use.

Great information. The only thing I can comment on here is that in the LED ENGIN spec sheets they show a migration away from 365nm when current is away from 300mA or 700mA. Between these 2 it is lower, under/over these numbers it is higher. So if you are driving the LZ-1 at 1000mA it should be around 3nm over 365nm, which is just about exactly where you show it. :wink:

Still, I’m pretty impressed with the SY-3535P emitter and will gladly use it in a similar small host when it arrives. Should see it any day now, as it’s been over 2 weeks since I ordered it.

Thank you for these tests, the graph information is exactly the kind of visual I need, as reading it all is somewhat confusing. :slight_smile: Gradually learning though, and largely due to your efforts. Again, Thank You!

Another useful review by djozz. :beer:
Int’l outdoor state it’s wavelength rating: 365-370nm, so about right. I guess your monochromator working perfectly, thanks for the bonus :smiley:

And it occurred to me, my Kaidomain P-60 drop-in may actually use the same emitter. It can use multiple cells but is limited to that 300mA range. The higher the Voltage in, the lower the mA out. So while this Intl-Outdoor emitter is on copper and can be run with a varied power supply, at similar output current it seems pretty much the same thing as the Kaidomain UV light.

I’ll get close-ups if possible when I have both in hand.

Edit: The Kaidomain emitter is a twin-emitter set-up, not anywhere close to the same…

Thanks for doing this testing. Looks like you had to use more ingenuity than usual, but I don’t see where you had to fudge very much. All your logic seems pretty well grounded to me.

And of course thanks for taking the time to write it all up and share it with us in such a good format.

Amazing work again djozz. Thanks heaps.

Thanks for the test. I should be getting one of these any day now for an A/C leak detection light build.

I went ahead and opened up the Kaidomain P-60 drop-in. They had an R150 current sense resistor on the buck driver, so I stacked an R056 on it. Put it back together with 22ga leads (it had like 28 ga)

Where it was pulling 300mA at the tail, it’s now pulling 470mA. And is considerably brighter! :slight_smile:

Thank you very much for the testing and writeup.

You write in such great detail and clarity about the considerations you make underway during your testing that it is always i pleasure for me to read these tests.



Thanks to you all for the nice comments again.

I have way more time to think of what I am going to do for the hobby and how and why, than I have actual hands-on time for testing and modding, I think that you can find that back in the write-up as lots of thoughts and considerations about what I did.

Without people like you and many others here none of us would have a grasp of this hobby.

so which centered gasket fit this led?
xpg or xml?
want to make a 16340 UVight :slight_smile:

The xp centering disc will work. It didn’t look right in a p60 so I didn’t use one. I just set the reflector over the led.

Just ordered a pair of these. Also ordered 2 of the same looking ones from an ebay seller to see if they’re the same.

Thanks for the testing and putting this all together.

CK, which ebay led? Can you give a link?

These have been popping up ebay for around $5 shipped - says 365nm as well. Anyone has tried these?

That looks like one mangled xb-d… like they pulled the dome off and scraped the phosphor ir…

I almost got those to but decided against them.

I got ebay item number 321464744098

So is it really 365 wave length as it said?
