Ultraviolet lamp Driver circuit

Hi team,

I have designed a ultraviolet lamp driver circuit. Use 3.3V DC input voltage and 120KHZ oscillating circuit as the input signal, Then use  the transformer to output 1000 AC voltage.

Then the ultraviolet lamp can be turned on, My questions are as below:

1. The  transformer size is very large(9.5mm*12mm). Do you have any other ideas to driver the ultraviolet lamp? Need 1000V AC voltage.

2. I do not know what can  affect light intensity? the ultraviolet lamp current or the ultraviolet lamp voltage? Do you have the similar experience?
