The 25w ballast can match the amount of daylight light bulbs
The products that are water-resistant, such as fish tanks, etc., etc., in turn, just want to make use of the lighting equipment on hand to make the lamp bright other than the other.
Some of the less known and inferior brand electronic ballast price low power use range is wide, some product itself power indicator within a certain range (15-30 w) general. It is suitable for low levels of consumer groups. (big brands are very strict ballasts matching high price can not be haphazard and avoid losses caused by!) Decades of practical experience have taught you that there is no textbook.
Now, that's one of the things that is very strict about matching two words; Not only the power must be matched but also the tube diameter of the lamp tube should be matched with the ballast, the flammable explosive places should be explosion-proof products
