Great Electronic ballast, works perfect for 250 Watt up to 1000 Watt HID bulbs, See pictures as follows: 1st pic - the 3 bulbs I will be using - 1000 W MH (from my previous job at Oakland Airport when they were Replacing bulbs with LED for the Airline Gates), in Center of pic, 400 Watt Mercury Vapor, on the Left, and a "Burned Out" 400 Watt MH from Work (Co office repair shop) on the Right side of pic. 2nd pic - 400 Watt MH arc tube close up with welding glass in front of camera. 3rd pic - 400 Watt Mercury Vapor street Light bulb (from about 1970's). 4th and 5th pic's - 1000 Watt bulb arc tube with and without Welding glass in front of Camera. (I used samsung S21+ phone for pictures. Note: there is a 12 Volt connector jack just above the wattage knob, but it is covered, and I have no idea what it is for, (Cover on it does not come off and No information available in the instruction sheet).Read full review

Works great, powers my 600w HPS lamp with ease. I definitely would recommend this ballast ! Lumatek makes great products. Has been running smoothly on a 15amp timer.
