Risk Reactor products have a range of wavelengths, features, and prices to suit any need. It might be confusing knowing which flashlight is best suited for your specific application. If you have a need for a UV flashlight, then you can choose between a single wavelength models or one that has selectable wavelengths.
When the wavelength decreases you will get two things. First, the contrast is improved and second the price of the LEDs increases pretty steeply. If you have a wavelength specification from the supplier of a dye product, then follow their recommendation and let us know what that is so we can help. The more LEDs, the more UV power is emitted (with the exception of the super xLamp models, where each LED die is very powerful by itself). For applications where you require multiple wavelengths in one unit, for example white, blue, and ultraviolet, then look at our multi-wavelength selectable units or send us your requirement specifications.
At crime scenes, having fast and accurate detection of possible traces is fundamentally important. Many bodily fluids and other organic and inorganic materials are fluorescent in nature.
To determine what light and wavelength you want review the application. Invisible Inks come in many colors. All Clear Blues can be seen with any of our UV Lights. The Clear Reds and Clear Yellow Invisible UV Inks require closer to 365 nm. So if you are using the MAR-C0 Invisible Blue Pen you can use any of the lights. The stronger the black light the brighter and farther you can see the invisible ink. Also the darker it is, the more you control the ambient light, the better the response.
380 nm - 390 nm
We carry everything from battery operated black lights, to plug in fixtures. The battery operated blacklites are perfect for outside and mobile applications. Use Risk Reactor's Black Lights to:
Money detector, theatrical, criminal analysis, mural making, art, rodent contamination detection, leak detection and quality control are just a few of the industries that use black light every day. We offer handheld portable blacklights to ultra violet spot lights. For example, our B33LEDM light can emit ultra violet energy over 40 feet. These powerful blacklights are used in situations where quality black light is needed for the right effect.
Passports All passports have various unseen multi-colored UV fluorescent emblems and images which will be revealed by the scanner, including The U.S. Immigration Service Date Stamp. Content will differ by Country. Casino Chips Casino chips can also be treated as currency in the casino environment so special UV markings are used. Many casino chips contain ID marks, which will fluoresce under UV light. Event Tickets of all types issue event tickets for music, sporting and other events, implement security features to stop counterfeiters.
When uv responsive traces are illuminated with one of our Ultra Violet lights of the right wavelength, the UV responsive surface will fluoresce and will be detectable to the investigator. Using goggles such as our UVGLASS1 Orange will give you another edge in the fight against crime.
UV black light fluorescent inspection lamps can be used for scientific
What is the difference between the bulb types?
There are two different factors in the bulb and there for the light cost. First is the wavelength. The lower the nm (Wavelength) usually the more cost in manufacturing such as 365 nm. 254 nm, which is short wave, is a lot more. Secondly, more intensity of the wavelength the higher the cost will be. These days has really spawned some great innovation creating high flux emitters which blows away traditional LEDs.
Does 365nm pick-up / show invisible ink etc... more intensely than 380-385nm versions?
Depends on the color. All Clear Blues Invisible Inks and Paints can be seen with a wide range of UV 360-395 nm. The Clear Reds and Clear Yellow Invisible UV Inks require closer to 365 nm. So if you are using the MAR-C0 Invisible Blue Pen you can use just about any of our Black Lights and UV LEDs. For the Clear Red you will need a 365 nm such as the BMAG-365.
Do the higher nm bulbs pump out more visible light thus interfering with the potential intensity of the items you are trying to fluoresce?
Yes. In the case of using Clear Blue Invisible Inks and Paints then 385 nm to 390 nm is fine for a strong response. If you want more contrast then yes, 365 nm is what you want.
How far away can the Black lights be from a fluorescing surface before it will "light it up?"
That all depends on a few factors. How bright is the UV responsive surface is, how dark is the area of inspection, and the type of black light.
I'm trying to make sure I get the right wavelength and strength of flashlight to light up invisible ink markers with the greatest amount of visibility and least amount of bleach-out due to the light itself.
To determine what light and wavelength you want review the application. Invisible Inks come in many colors. All Clear Blues can be seen with any of our UV Lights. All visible Paints and Pigments can be seen with any of the lights as well. The higher the nm you will get more of that “flushed-out” or “bleached-out” effect. But if you are using the MAR-C0 Invisible Blue Pen, which can be used with any of the lights, then 365 nm lights would give the largest visible difference but most clients use the 395 Lantern in large inspection area applications.
