1) Amount of Heat Produces. - T5 less
2) Cost for Tubes ; say base on 36W PL and 39W T5HO - T5 cheaper in long run, infact quite cheap in short run too

eg for 2ft tank. one 36W PL tube is short and may not have adequate coverage of tank. one T5 24W HO emits lumens comparable to 36WPL, have better coverage (tube length) and last longer.

3) Lifespan - T5 last longer
4) Your Personal Preference. - T5 better
