Prolong the life of glue boards with refleckobakt sleeves. Thin designs and longer lasting glue boards are made possible thanks to the reflectobakt sleeve available in t5 (5/8″), t8 (1″) and t12 (1-1/2″). This sleeve shields the full-sized glue board from the drying effect of the uv light, thus making the systems more effective for longer periods of time. Note: don’t throw the reflectobakt sleeves away!! remove them from the spent lamps and place them on the fresh replacement lamps for optimal performance.
