Show your Caterpillar Lab pride with the Lab branded UV flashlight! *Our flashlights are selling out fast, but we expect to restock within a few weeks! Having learned about using U V lights to look for caterpillars from a teacher in Ohio in 2016, The Caterpillar Lab brought this past time to the attention of the natural history community and has championed it over the years since! Many caterpillars fluoresce under ultraviolet light. This simple technique helps naturalists spot species that might otherwise go unnoticed – and now you can discover them, too! Why This UV Flashlight?For more than a decade, The Caterpillar Lab has tested a broad range of UV flashlights and watched the technology improve dramatically. The lights we’re offering today combine the features we value most for field caterpillaring—outperforming many models that are larger, more expensive, or heavily marketed.Key Advantages• True 365 nm wavelength Produces stronger, more reliable fluorescence than 395 nm lights; preferred by TCL staff and many field naturalists.• High-intensity new-generation UV diodes Illuminate caterpillars at greater distances; far more effective than older, multi-LED “flat-top” designs.• Stable, non-overheating performance Unlike many UV lights that shut down after minutes of use, these remain steady through extended field sessions.• USB charging built into the flashlight Charges like a phone—no battery removal or external charger.• Field-friendly design Battery-life indicator, compact size, lighter than similarly bright lights, and reasonably priced for a tool you may carry (or lose) in the field.Known Drawbacks Battery indicator can behave inconsistently. Power button can get sticky with heavy use. These issues haven’t significantly reduced the usable life of our lights. Why We Sell ThemAfter years of testing, these lights offer the best balance of power, stability, portability, rechargeability, and cost. They’re the ones we trust and carry nightly—and they transform any backyard or trail into a UV caterpillar adventure.
