I think if you view the bulb/ballast comparison data available on USA websites, it is clear that electronic ballasts run the bulbs at a lower wattage, this tends to be reflected in the brigtness of the bulb. the HQI ballasts draw more watts and are brighter.
Is that not correct? |

Its not recommended that bulbs should be overdrived. It will only shorten the lifespan and risk failure with that little extra brightness. |
