Low-watt USB UV blacklights for insect traps
Available sizes
Lower wattage allows for longer run times, or smaller power banks.
Optional day/night sensor
Automatically turns the light on at night and off during the day for multi-night, unattended operation.

For extended outdoor use, especially in rainy conditions, seal the sensor and power supply in a transparent, UV-resistant enclosure.
We tested runtimes across multiple portable power banks. View the full results (PDF) →
These power banks are designed to stay on continuously, allowing your light to run for multiple nights while unattended. Runtime depends on both the wattage of the light and the capacity of the power bank. This is not an exhaustive list, and other “always-on” power banks may provide similar results.
Voltaic Systems “always-on” power banks won’t turn off when no power is being drawn.
Take the Wh (watt hours) and divide by the light’s wattage to get approximate run time.
Note: Building a custom system requires some technical knowledge and may involve modifying connections.
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.
