Quick note from the bench, since UV questions come up around Halloween season. 365 vs 395nm is not about which is "stronger" - they are different wavelengths, and the visible difference is huge. 395nm puts out a lot of visible purple light, so your prop looks lit but the fluorescent pop gets...

Both exist, and the difference matters more than the price. Most UV strips (ours included) are “dumb”: constant-current, 2-wire, run straight off 12/24V. You can dim them with any standard PWM dimmer, but UV emitters lose efficiency and drift at low duty cycles — below roughly 30% on the dial...

Hi everyone — Shicheng here. I run a small LED workshop in Shenzhen building specialty-wavelength strips (365nm UV, 660nm deep red, 850/940nm IR), and I have been lurking here for a while — the animated Christmas displays you all build are on another level. Looking forward to learning about...
