395nm UV LED Strip

A 395nm UV LED strip produces a visible, soft violet or deep purple glow. While most ultraviolet light is invisible to the human eye, 395nm is right on the edge of the visible spectrum, so you'll see some of its output. This visible light is normal and doesn't mean the strip is broken. The main effect, however, is the invisible UV-A light that actually makes fluorescent materials pop.

Go with 395nm for general use like finding pet urine. Most organic fluids fluoresce brightly enough under 395nm light, and these strips are more cost-effective. A 365nm strip will make them fluoresce even more intensely with higher contrast because it emits less visible violet light, but for most household tasks, 395nm is perfectly fine and gets the job done.

Yes, our 395nm UV LED strips are excellent for automotive leak detection when used with UV-sensitive dyes. The flexible strip lets you get light into tight spaces in an engine bay that a traditional bulb can't reach. Just power it off the car's 12V system. For the absolute highest contrast, a 365nm light is technically superior, but 395nm is the workhorse for this kind of diagnostics.

The peak wavelength for our 395nm UV light strips is centered right at 395-398 nanometers, with a typical tolerance of +/- 11nm. This means the output is concentrated in the 385-406nm or 387nm-409nm range. 

You definitely can, as long as you choose the right strip. A standard USB port outputs 5V DC, so you'll need one of our DC5V LED strips to match. Don't try to connect a 12V or 24V strip to a 5V source; it won't light up. Check the power bank's output amperage and the strip's wattage per meter to make sure you have enough juice.

Yes, it can. All UV light, including the UVA from a 395nm blacklight, can cause fading and degradation in pigments and materials over long periods of exposure. For a temporary party, it's no big deal. But for a permanent art installation or display case, you should be aware that it will accelerate aging compared to standard visible light. It's much less damaging than direct sunlight, but the effect isn't zero.

Yes, we can build that for you. A huge amount of the product we ship is built to a customer's drawing. You can specify the exact length, the IP rating (like IP67 for outdoor use), the type and length of the wire leads, and even the specific connector you need. Just send our engineers a quick sketch or description of what you need. We'll send back a complete wiring plan and quote, usually within 12 hours, with no obligation to order.

The most popular use for 395nm UV LED strips is creating black light effects for parties, glow-in-the-dark art, and stage productions. They're also widely used for inspection purposes, like detecting counterfeit currency, finding pet stains on carpets, spotting leaks with fluorescent dye, and curing certain UV resins and glues. Basically, anywhere you need to make something fluoresce, this is the tool for the job.
