A buddy of mine gave me 2 25 watt PC bulbs. I have an Incandescent hood laying around I could put them in. I question the bulb because they are only 2700K. Lumens are 1250. What would be the effect of putting these on a 20 gallon planted tank? Is the 2700K inviting algae growth?

I do not think you will see the kind of growht you are looking for. It will be a very yellow weird looking tank if you use these lights. I do not think it will invite algae for any other reason than poor plant growth.

So is 50 watts at 2700K better or worse than 20 watts at 6500K?

I dont know. Sorry i cannot have an answer. If i was in that perdicament i would use the 50 watts. The kelvin doesn't mean much. It is just a overall assumption on the lights color. Incandescent bulbs will never be as good for plants as flourescent bulbs. Because flourescents can be changed to better suit plant needs.

I've read in other threads of someone having ok growing results using these warm white bulbs. But I wouldn't enjoy looking at a tank under those lights...way to orange to look good.
