Powerful Lab UV Lamp 6W x2 254nm + 365nm UVA + UVC 120-240V AC Powered AAdvance Instruments AI-3UV20

• Durable and powerful 6W x2 254 + 365nm dual wavelength UV lamp. Model number: AI-3UV20. Universal broad range 120-240 V AC 50-60 Hz input. This lamp uses two G6T5 6W bulbs, one each for 254 nm and 365 nm. The 2 wavelengths can be powered on at the same time if desired..
• FREE EXTRA OPTION: This lamp can be used as 254 nm x2 or 365 nm x2, according to the bulb. If desired, we can prepare the unit for exclusive 254 nm (double the power, 6W x2) or 365 nm with no extra fee. This may be very useful if your application only needs one wavelength, while you can get double the lighting intensity (when powering on both bulbs at the same time). Simply send us a message before or right after your purchase..

uvBeast New V3 365nm Black Light UV Flashlight – HIGH Definition Ultraviolet - HIGH Power and Long Range Professional Grade Beam Best for Professional/Commercial Use – USA Stock

• ...atteries are pre-installed in the equipment and the insulation tab needs to be removed.
• WHY uvBeast V3 365nm? Our users wanted more intense 365nm UV and more range for better results. Our new design intentionally aims to fill those gaps. (1) The popular and in-demand V3 spec now emits even higher quality UV at 365nm wavelength. (2) More bang for your buck with filtered UV. This isn’t cheaper unfiltered UV. (3) Unbeatable long range (60 feet+) and a high intensity 365nm beam unlike others..
• PROFESSIONAL GRADE FILTERED 365nm. This is filtered 365nm wavelength that professionals and specialists use. We know. We supply them. This is NOT to be confused with longer wave 395nm devices. Nor is it to be confused with unfiltered 365nm UV. Most excitation occurs at 365nm which means you’re getting superior results to most users. 395nm cannot compete with 365nm devices. The on-board UV filter blocks unwanted visible light but allows max transmission of pure 365nm UV. This is UV at its purest.
• OUR HIGHEST INTENSITY 365nm DEVICE. Higher than most 365nm devices currently on the market. 365nm is the gold standard for UV flashlights. Choice is mostly restricted to the smaller single 365nm LED flashlights which are not as powerful as the 395nm longer wavelength units....

UV Lamp 6W 254nm + 365nm Handheld Portable Shortwave + Longwave UVA UVC Li-ion Battery/DC Powered AAdvance Instruments AI2UV20DC

• Exquisite Li-ion battery / DC powered 254 + 365nm dual wavelength UV lamp. Model number: AI-2UV20DC. This lamp uses two G6T5 6W bulbs, one each for 254 nm and 365 nm. Being battery powered and cordless makes it especially convenient for many applications difficult with an AC powered plug-in UV lamp. At the same time, this lamp can also be used with the power plugged in, like a laptop computer..
• FREE EXTRA OPTION: This lamp can be used as 254 nm x2 (shortwave, UVC) or 365 nm x2 (longwave, UVA), according to the bulb. If desired, we can prepare the unit for exclusive 254 nm (double the brightness, 6W bulb x2) or 365 nm with no extra fee. This may be very useful if your application only needs one wavelength, while you can get double the lighting intensity (when powering on both bulbs at the same time). Simply send us a message before or right after your purchase..
