HID CFL equivalent?

How many watts of CFL light do you need to equal a 150 watt HPS?
I'm planning on getting 3, 2700k, 68 watt (300 watt equivalent) spiral CFL's.
So thats 204 watts then i was going to add 2, 5600k, 27 watt spiral CFL's.
That's a total of 258 watts and 15800 lumens (27 watt is 1600 lumens/68 watt is 4200 lumens).So would this be equal to like a 150 watt HPS? Because the lights have a more spread out light foot-print.

Also, as a side note, I am growing in a 2 ft wide, 4 ft tall, and 1.5 ft forward grow space. It has good ventilation (supplemented by C02) with an oscillating fan, flat white painted walls. I will be using the ScrOG method as well as LST'ing my plants before they are old enough to be placed in the ScrOG screen. I will have 3 plants all in 1 gallon pots. How much do you think i will yield?

im guessing so. i have almost the same set up as you. 15000+ lumens so yea it should be the same as an hps. the only thing is hps put out a color of 1800-2000k. they dont make any cfl that low in the color spectrum. :(
 
But the lowest CFL kelvin temp. (2700k) is the precise equivalent to the sun's kelvin temp in july through september which is the majority of the flowering photoperiod.
 
oh yea? nice to know!!! but apparently hps produce the ideal type of bud that some say cfls cant match. fuck em' ill stick with cfl all day. dont get me wrong if someone wanted to hand me 400w or even a 250 i would def use it for flowering. and i think the sun produces better buds cuz of all the uv and diff spectrums it puts out. so i think its a great idea if we all used soe type of uvb lighting during flowering.
 
But marijuana plants do not benefit from ultraviolet rays, however it does help penetrate the useful light towards lower bud sites. Haha i would get a HID in a heartbeat if i wasn't so worried about burning my house down. CFL's for me are even a little iffy.
