It's the amount of energy and the spectrum it is in that counts. LED's are about 90% to 95% efficient, so a 14 Watt LED module emits about 13 Watts. Likewise, a 54 Watt T5(HO) fluorescent bulb emits about 48 Watts.
Now to compare the purchase cost per Watt:
$8 for a 54-Watt T5HO --> about 15 cents per Watt.
$35 for a 13.8 Watt LED module --> about $2.54 per Watt.
