600w bulb Q's

Hi, I am in the market for a 600w bulb. I found a 600w dual arc on ebay for $40 that I am considering. It is that or I am looking at like a hortilux or something along the lines of an enhanced HPS bulb. Has anyone used a dual arc 600w. it is 300w MH and 300w HPS in one, but it only puts out 61,000 lumens vs the 90,000 avg of highend HPS bulbs. what do you think the best option is for a whole grow cycle, 5 weeks veg 8-10 flower? thanks for all input in advance.

i've seen good bulbs go for 80 plus dollars for a 600 watt.

i think since you already have a really nice light why not go the extra mile and spend twice as much and get the nicer bulb

i'm not saying spend 80 bucks on a light if you have you know how to get a good light for cheaper. but if you dont then gotta cough up the cash

you're going to grow watermelons

personally i prefer 3 months veg. then 2 months flower.

I dont really have a problem spending the cash but I have read some stuff on the 1000w dual arcs and there are suppose to be excellent. I have never seen the one for 600s until now. I just trying to figure out what one I would benefit more from the dual arc or enhaced HPS.
