The screw in 50/50 bulbs are pretty much useless.
Daylight ~6500k spiral lamps would be better for your tank then 5000k. Two would be my normal recommendation for a 10g tank.
Don't place them close enough to the water to be easily splashed. They should never get hot enough to shatter, but too close might make tank maintenance more of a problem then it should be.
