Which is better. PL light or those with E27 type mounting ? Was deciding on the type of light when came across this two different type. One is long and thin and the other is shorter but round or 'Fat'. Given the same wattage and type ( Cool Day Light ), which is better?

PL comes with balast, will brighten immediately. Tend to be more expensive.

E27 easier to change bulb, cheap, but takes a while to get to full brightness.

PL with the balast tend to be hot after awhile right. As the E27 Lamp comes with built in E-balast is cooler right ?
