I use $30 bulbs, in faceted my 600w is cheap bulb, and I have a eye hortilux in my other, both are making nice fat buds.
Lumens, is not really what to look for in a bulb.
I'm a new grower still, but one thing I learned is lumens is just part of the story, of a good bulb.
I'll I can see out of the bulbs is that the hortilux has a more white light, then my cheaper bulb.But as far as bulbs, the buds, look the same?
The Hortilux is just an enhanced spectrum bulb, so it adds more blue spectrum while lit up than a regular HPS bulb.
The added blue helps a bit with reducing stretch (so it's claimed) and gives a small boost to the overall spectrum that our plants crave.
I don't doubt that it works as advertised for the most part, just not sure it's worth the extra cost because it's all I've used for 4 years.
Definitely want to try a grow with a normal HPS bulb just to see for myself if it's worth it.
But, again, some of the guys in the 600 use "no-name" HPS bulbs from Lowes/Home Depot places, and I've had the privilege of sampling their buds, and it's just as good as any I grow (or better), and the pics are always being posted here in the 600, and you would never know it was grown using a bulb that cost less than $50 compared to a $70 to $100 name brand bulb.
So, too-long-of-a-story-short: it's 6 of one, half dozen of the other. If you have the extra money, then buy whatever makes you happy. But if you're on a budget, you shouldn't worry or feel bad about a decent bargain bulb, because it's going to do you just fine. And if you find good deals on the internet for the high-end bulbs, then jump on it, because you never know when the price will get jacked up, or a sale price will end.
I'm waiting on an Apollo 600 watter to get here.... It should be here by monday...I've got 208 CFL watts on them right now in a DR150 II and I can't wait to be a part of CLub 600!
My first two grows were using household CFL bulbs.
Used 8 of the 23watt bulbs, and got about a half an ounce of killer weed off of the first plant I grew, and then 3/4 of an ounce of the second plant.
With a 600watt, I'm up to about 1.5-ounces per plant to 2-ounces per plant, and can fit 5 to 8 of those plants in a 4x4 grow space, depending on how big I want to veg them.
My new closet is only 2x3 feet, and I can still fit 5 or 6 plants in there, and should still be able to get 1 to 2 ounces per plant (fingers crossed).
Looking forward to seeing your grows as they progress!
We always need new seedling/veg/flowering/bud/smoke pR0n here in the 600
