Shortwave and Longwave Ultraviolet Lamp

Item# RM-SWLAMP

This economical shortwave ultraviolet fluorescent lamp now also includes a longwave ultraviolet LED lamp so you can experiment with both shortwave and longwave ultraviolet light. Shortwave ultraviolet light is just the right wavelength to vibrantly illuminate many fluorescent minerals that you collect. Some minerals fluoresce, or glow, under shortwave ultraviolet light, others under longwave ultraviolet light, and others fluoresce differently under both!

This one economical, portable provides both shortwave and longwave light, making it a good investment for a rock collector. This lamp produces fluorescent shortwave light at 4 watts and 254nm wavelength and it produces LED longwave light at 375nm wavelength. You provide four AA batteries.

Note: UV light is the part of sun light that causes sunburns. Never look directly at UV bulbs. Wear UV filtering goggles or glasses if using this low-level ultraviolet light source for extended periods.

Quick Science Investigation: Are you wondering if your safety goggles, sunglasses, or regular glasses will help protect your eyes against low-level ultraviolet light like our battery-operated UV lights? Many of these types of glasses have lenses made out of polycarbonate, a natural low-level UV light filter. Test your goggles or glasses by first shining a UV (shortwave or longwave) light on a mineral or other object that fluoresces brightly. Then put the UV lamp inside the goggles or glasses and shine it on the same fluorescing object through the lens. What happens? The object will no longer fluoresce where the UV light has been filtered by polycarbonate lenses!

Useful and handy Review by
My application is slightly different than most. Part of my research deals with carnivorous plants. Many of these plants will fluoresce under short wave UV light. While this unit may seem a little underpowered, it is portable, battery operated, and dual band. I Have found it very difficult to find a similar unit for such a reasonable price. So far, this lamp has worked just fine for me in the lab, the greenhouse, and in the field. I agree with other reviewers that the switch design could be better, but the sliding action has been stiff enough that I have yet to have any problems with it turning itself on. You also need things to be pretty dark. However, the combination of price, dual bands, and portability has made this lamp a worthwhile addition to my equipment.
Good value Review by
My 9 year old grandson loves it. Perfect gift for an aspiring geologist. Excellent starter lamp. I highly recommend it.
Great Buy Review by
Great little lamp for the price. It works perfectly for the small flourescent mineral display we are making for a science project. Excellent starter lamp.
Wow! Review by
I bought one for use at school with our 6th grade science students to see if it would work for our rocks and minerals section. It not only is a GREAT UV lamp, the price is phenomenal for a duel frequency black light. We will be buying more shortly so each lab station has one. The only thing it could use is a plug in DC source. I modified my own unit to work off a DC power supply. The only "complaint" is the switch does not have a center detent but for the price; Who cares?! This is a great tool for classroom, field or hobby use.
Small and a little flimsy Review by
I pray this works. It is very small and flimsy for the price.
