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.
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. Gradually learning though, and largely due to your efforts. Again, Thank You!
Another useful review by djozz.
Int’l outdoor state it’s wavelength rating: 365-370nm, so about right. I guess your monochromator working perfectly, thanks for the bonus
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.
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!
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.
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.
I would love to see how the KD P60 drop-in (with two cells) compares against the two emitters in the OP. The KD drop-in (two emitters under one dome) already works significantly better than anything else I’ve tried, and if the two in the OP work even better still, that’s pretty exciting.
Those UF-602C hosts are great for small mods and I’d love to use one for UV instead of the relatively huge SF-L2m I’m using now.
