will high wattage bulbs melt my strip light?
this might sound like a silly question,but... will a high wattage bulb melt my strip light? i have a 48'' strip light that holds two 24'' bulbs.a lady at my local fish store told me, i don`t have enought wattage to grow certain fresh water plants they sell.she said with the lighting i have now the plants will grow,but won`t change colors to the browns or purples i see in their store.
i have two 20 watt 24'' bulbs that say they are made for growing and maintaining fresh water plants.the bulbs say they have the spectrum of color the plants need.the lady informed me,i would need 3 watts of light per gallon of water.i have a 75 gallon,i would need 225 watts of light right? would this amount of power melt my strip light?
i do have a spare 48'' strip light.could i use this to add light to my tank,using different bulbs? any help would be great. thanks paul.

The WPG rules stinks!!!!! Wattage is a measurement of enrgy. Example, wattage is heat, heat is energy, therefore, wattage is energy.

You need a bulb that is highly efficient, ie. highest lumens at the lowest possible wattage. But the bulb should also emit light that the plants can use. So, now spectrum comes into play.

The most important things in selecting lighting for the planted tank are intensity(lumens) and spectrum. Wattage is not important.

To answer your question, that much heat will probably melt your plastic fixture. Definitely will warp the deflector if it's plastic.

Input your tank size in there and go from there. Is much better for determining light levels than W/G. Regardless though you have to remember that you need quality lighting in the right spectrum or all the watts in the world won't help you.
