This is what this CFL bulb reads and i dont know what it means. I found it in my house and i want to know if its okay before i go out and buy another one. I just have one plant in a foot by foot area. This is what it says: 12w/19w/28w 230/320/470mA 120VAC 60Hz
I THINK you may have a "3 stage" lightbulb .. there are light fixtures that allow you to turn the light up, or turn the light down, LIKE "mood lighting" its 12w on low 19w on med 28w on high i think.
i have no clue i wouldnt get another one of those just get a 23 watt 6500 daylight bulb n add more as u go that might be alright for veg but who knows for flowering get something that is known but it might work is ur plant stretching for light if its not it will probably work
