With an optimized spectrum matching the eye sensitivity of the housefly, Actinic BL TL-D(K) Secura lamps are perfect for attracting insects. They have virtually no UV-B output, and so are perfectly safe. In addition, they have a special "Secura" sleeve that keeps all glass and components together in the case of accidental breakage. This eliminates the risk of glass splinters showering down on food preparation areas, for example. And that is why it meets the strict HACCP requirements. What's more, with the lowest mercury content in the industry and being 100% lead-free, these lamps represent a very good environmental choice.
