2015 ff self ballasted Mercury lamp with sheet

this is the set currently in use. Located under a balcony, in a corner such that neighbors cannot directly see the bulb. The light is on the sheet, but also in a 60 degree angle towards a South facing slope with dry grassland which I established in my back yard. In about 30m distance the forest starts. The stand was home made from water piping, cable and lamp holder. The side arm was used to hold an umbrella to protect the lamp from rain. WARNING: I am wearing glasses! Protect your eyes and don't look into the light!

sometimes, I use UV LEDs in addition, to attract micro lepidoptera to a specific location near the bottom of the sheet. here shown with the Mercury lamp off
