Hello All, I have a VL2500 Spot fixture that occasionally while operating the light will start pulsing. The light will pulse for a few minutes and then become steady, It will continue to alternate between pulsing and steady through the duration of it's use. It roughly spends about 2/3rd's of it's time steady and 1/3rd pulsing. This same fixture will also occasionally lamp itself off and then after about 1.5 minutes will automatically re-lamp. Other than light output the fixture continues to function normally. Any guidance or direction would be very helpful and appreciated. Thank you in advance!
