Hqi Vs Standard

[PoriferaBob]

What is the difference (pro's and con's) between HQI halides and the standard mogul and bulbs???? Ive been searching the net for comparisons of the two and cant find anything??

 

[michaeldaly]

Not really much difference.
HQI are usally slightly more intense. But, they also need to be sheilded for uv as they dont have built in uv protection

 

[PoriferaBob]

Hey michaeldaly!!! Intense in what way? They just LOOK brighter? Why would you think that they are so much more expensive then?

 

[PatrickJ]

Standard is way better. No comparison.

I am running both hqi and mogul based bulb's on my 120 to see the difference.

One one side of the tank is a 250W HQI IC 10K XM, the other is a 250W Iwasaki 6.5k bulb.

Both of them have enough strength to reach the bottom fine. The Iwasaki is yellower than the XM.

I should be able to tell in the next few months how much color and growth are affected.

Sorry about that last post......

pwachs!! That is gonna be very interesting!!! I cant wait to see what happens!!!

I've seen some dealer websites that compare 250 HQI's to 400 watt standard.

Here is an example.

I'm going with 250 HQI. Plus with HQI you don't have to worry about your reflectors getting pitted and stained from salt splash because of the glass cover.

That's my lame brain thoughts.

Dude, how are you gonna have a valid comparison if you use different brands of bulbs and different kelvin ratings?

I was thinking the same^

my 150w hqis but appear just as bright as my 250w SE --- that's a 100w in power savings.

Here's my tank: the left and center bulbs are both 150w HQIs (double ended)-14k and the right side is 250w mogul (single ended)-15K

can you take a picture with the middle hqi off?

Now thats not really fair, you should try running them both at 10k for an accurate comparison.

Im running duel 150 hqi's and my tank grows very well and is extremely bright.

Hands down. You cannot beat what a graph will tell you.

I even gave it an M80 ballast for best perfomance and put the single end on a cheap M57.




Try all you want, but 9 times out of 10, Single ended is best. Hands down.

Want more? Heres a 250 watt example. NO CONTEST

Single ends are much brighter and if you can read a graph, understand numbers, you will get it too.

 

[leeweber85]

Patrick does that graph show the PAR difference?

 

[PatrickJ]

PPFD = PAR

That is for all pratical purposes.

 

[PatrickJ]

Efficiency is calculated by "PPFD" / "Power" = "Efficiency"

Power is what was actually used and varies ballast to ballast.
