Dude. Google is your friend. Large hoods are fucking stupid. Especially the really long ones. Do you have some magical 30" long hps bulb to utilize a 3' long hood?
Look at the greeners test. Those big ass hoods scored below the others

Agreed, I would say anything that's batwing that's not well-overblown should work decently for most... you don't need a reflector that's capable of throwing light 18ft across the room, given the laws surrounding it.

i personally think this test is shit, without having some par and FC readings we can look at.

Yeah great point...because a measure of par spread would having nothing to do with the spread of lumens?? Did you actually think before posting, or just impulsively dismiss their test because it didn't jive with your understanding?
And just a an FYI so you don't seem so stupid in the future, lumens or lux are the same thing as foot candles, one is just referenced to an area.

okay?? be a jackass over nothing..
my point being they dont show any results other than the "efficiency" number that they give.
what does this mean to me. maybe the difference in real numbers is minimal. maybe its big enough that i would want to switch.
but why would I want to make a decision without the actual readings.
when did I say FC was different than lumens?

They measured lux in the test and you said they wished they measured FC.... Which is essentially the same thing. PAR is radiation, just as light is. Therefore the efficiency and light spread in the inner and outer perimeters should be directly idicative of how well the light energy is reflected downward.
Bottom line, some people like to dial their shit in based on their style of grow, some want to but dont have the funds and yet others are just easily swayed by marketing. I mean, look how many people still buy magnetic ballasts. Why someone would do that is beyond me.
The biggest hood? Probably the viper.

Efficiency makes more sense, because there is too much variables between different bulbs to give any real world numbers. Efficiency makes more sense, because it isolates only the efficiency of the reflector. I'm currently running a 400w CMH in a Blockbuster reflector. If they gave some fort of lumen number for HPS, it would be meaningless to my situation.

It doesn't matter what kind of bulb your using, the hoods reflect how they reflect. The test is a COMPARISON amount different hoods using the same bulb, ballast and height. You need to look at the outer and inner numbers to see how even or concentrated they are.
You don't need par or need to know what the output for your exact bulb is. A shitty reflector (cool tube anyone?) is a shitty reflector. Period.

I went heavy duty industrial on my bonnet. Cast aluminum and bullet proof glass, if you got the change go industrial and forget about those cheesy grow bonnets. Most of them are just gimmicks.
