Review on Mosquito Replacement 21050 Zapper Lumenivo by Richard Messar

Although they appear identical to DynaTrap lamp #21050, all 3 did not work for me when first installed in a DynaTrap unit. Do they glow slightly and look like sparks? - Watch the video and watch out for intermittent white flashes. If you move the bulb back and forth once it's in you can get it to glow properly so I kept my order as I need the bulbs but not sure if they will last. Tried 3 bulbs in 2 different DynaTrace DT3019 devices, behaved the same way. A working old DynaTrap light comes on.
