Description of LepiLED

The lamp is designed for the attraction of nocturnal Lepidoptera and other insects, and it is very efficient, lightweight (c. 410 g including cable), handy and robust. The lamp is especially suitable for working in remote areas, and the equipment can easily be transported in backpacks and on air planes.

LepiLED is made of anodized aluminium and a borosilicate glass cylinder. The cooling system is passive and the lamp is almost waterproof. It is recommended protect batteries from rain, e.g. by using plastic bags or containers. Borosilicate glass (3 mm) is long-lived and tough. The emitted radiation is intense, and some people feel dazzled. When used behind gauze, the dazzling is less intense (but gauze tends to absorp UV radiation). Bubble wrap is also useful against dazzling. Glass-cylinders can be replaced with a clear plexiglas (=acrylic) cylider.

The lamp can be operated with a voltage between 5 and 13 V DC. The lamp is equipped with a 2 meter cable with USB plug, optimized for the use with powerbank batteries. Such batteries (e.g. easy acc 26 Ah) can provide power for about 10 hours (standard model).

Other batteries (such as 12 V lead batteries) can be used with the available adapter. Powerbank batteries can easily be recharged with a standard USB charger (as used for mobile phones). They can also be recharged with mobile solar panels in remote areas. Note that the maxi model requires 2.7 Ampere (2.5 are ok in most cases). Recommended: QC 3.0 (Quick Charge) chargers provide 3 Ampere.

A lightweight polypropylene funnel trap with net designed for LepiLED is available for 49 Euros.

LepiLED is now offered in four versions: Mini, Standard, Maxi, and Maxi Switch. The table provides an overview. All lamps look very similar; the mini model is a bit smaller and the maxi switch can be switched between UV mode and mixed radiation mode. This allows to collect 'invisibly' and safe energy if required.
