I'll find this list of the lumens output some guy did of all the different size an dtypes of fluros, higher the lumens, the closer to being the sun it is.
The ones I have used put out about 3500 lumens and from reading here some of the more experience boys say anything under about 5000 isn't too impressive.
Maybe some daylight for week might show if its a light prob or not?
