NEW: 11 watt Shortwave and Longwave Ultraviolet lamp. This UV lamp design has been our most popular for well over a decade. Our main customer base are individuals interested in fluorescent minerals. We may be new to Amazon but have been providing UV lighting products since 2002. Did you know that well over 90 percent of fluorescent minerals need a filtered shortwave UV light source in order to glow properly? Fluorescent minerals can be found from all over the world and are commonly enjoyed by young and mature alike. Almost all fluorescent minerals respond best in the dark and will require a shortwave UV light source that has a UV-Pass optical filter included. The costly made specialized shortwave filter blocks out the unwanted purple visible light generated by the fluorescent tube or LED light source. Shortwave UV lights are not blacklights aka longwave UV light sources (ideally 365nm). We understand there is a lot of confusion when it comes to choosing the right type of UV light when collecting for fluorescent minerals. A brief descriptive tutorial pertaining to UV light will help minimize the confusion and avoid confused buyers with choosing the wrong UV lamp. We understand there is a lot of confusion when it comes to choosing the right type of UV light when collecting for fluorescent minerals. A brief tutorial explanation abouto UV light will help minimize the confusion and help you avoid purchasing the wrong UV light. Unfortunately there is a lot of missinformation and missleading images by many suppliers. We are a specialized American based UV lighting company with well over 23 years experience in the ultraviolet lighting industry. We strive to stand out from other supplier by providing prompt customer service and going that extra mile with added value products and service. To help earn your business we have included fluorescent mineral samples with our UV lamps. The minerals respond in a variety of colors and some will even glow for a few seconds after the UV lamp has been turned off! The sample bag is 3"x 3 1/2" inches in size. The mineral specimens vary greatly, but we try and provide unique and eye catching cool samples. A common question from our potential buyers is what type of shortwave UV light source is best? UV LED or UV fluorescent tube? UV LED lamps will produce a focused output beam of UV much like what you see when using a white light LED flashlight. Fluorescent tube style UV lamps produce a more flooded output effect vs a concentrated beam effect which is what you see in UV LEDs. Our UV lamp is a flood style lamp that also uses a specialized UV tuned polished metal reflector that helps maximize the UV energy being produced. Both types of UV light sources perform best in dark conditions and should have the specialized UV-Pass optics filter in order to help block out most of the visible light. Having a flood style output lamp is what many of our customers prefer although some of our other customers who prefer LED style do in part because of their compact size as compared to the size of larger style fluorescent tube lamps. The key point to remember is the need for filtered shortwave UV is need to see at least 90 percent of fluorescent minerals. The remaining longwave responding minerals do best with filtered 365nm longwave UV. It is highly not recommended to choose any other longwave flashlight above 365nm. Many sellers offer 385/395nm flashlights that may seem appealing do to low cost. They are very old technology that produce a large amount purple light and do not use any UV filter. Some come with multiple LEDs but that does not translate into stronger output flashlights. A single LED 365nm longwave flashlight can easily out perform a 50 or even 100 LED 395nm flashlight many times over. When it comes to longwave LED technology it has been around for over 20 years and have developed to the ideal 365nm for almost all applications. Trust in us with our UV experence and technical know-how. We have included a extra longwave 365nm fluorescent bulb. Please note only one fluorescent tube can be used at a given time. This requires the exchanging of the bulbs manually within the base of the lamp. The lamp also includes a white light LED on the side. Users enjoy the white light flashlight to help them while hunting for fluorescent minerals in the dark. The lamp easily switches from white light to UV with the flick of the switch. Specialized ANSI Z.71 UV-C blocking safety goggles also included to help protect your eyes from shortwave UV and help the eyes from any rock chips while breaking apart rocks in the field.
