USB-powered UV LED blacklight for portable insect work
The Entoquip Light USB draws 2.4 amps. Some smaller power banks are limited to 2 amps and will not power this light. Use a power bank or USB adapter rated for at least 3 amps.

What to expect in the field
Many users power the USB light with 100 Wh power banks, which are permitted in carry-on luggage for air travel. A quality unit typically provides ~6–7 hours of runtime. Actual runtime will vary by manufacturer, as not all deliver their rated capacity.

Night-flying insects orient using distant celestial light sources, particularly the moon and UV-rich night sky, and are most sensitive to UV-A wavelengths (315–400 nm). Artificial UV-A lights act as closer orientation cues, disrupting navigation and causing circling and frequent landings near the light, especially on moonless nights. Modern LED technology enable emission at 365 nm and 395 nm, which Entoquip lights combine for broad UV-A coverage.
The spectra below compare moonlight with 365 nm and 395 nm UV-A LEDs.

Entoquip lights emit wavelengths within the long-wave ultraviolet range. These wavelengths are naturally present in outdoor light, and the emitted intensity is lower than direct daytime sunlight. As with any bright light source, avoid looking directly at the LEDs. UV-filtering eyewear may be used for added comfort during prolonged use.
Entoquip lights use a high density of LEDs, which means they will get hot to the touch during operation. Surface temperatures typically reach 140–150°F (60–66°C) depending on ambient conditions. This is normal for high-power LED systems. Avoid handling the light while it is running and allow it to cool before repositioning.
