Eye Hortilux Vs. Regular HPS bulb

[narutonut]

I was running no name 1kw hps bulbs in my grow. I got a 1kw Hortilux eye super blue HPS and all I can say is wow. At $180 a bulb they are spendy but the 2oz per plant increase more than off sets the cost. Really cool lamp cant wait to see how the second light I'm dropping in after this run blows stuff up.

Has anyne here compared the Eye Hortilux vs Phillips CHM?

The Phillips CMH seems to have a far superior spectral distribution curve

Quantum

I burnt up 7 of my 8 Hortilux bulbs in Quantums in less than 4 months, I would have to respectfully disagree. Ushio for digital ballasts to be safe, Hortilux Eye for magnetics.

Also, if you have a switchable magnetic, I'd urge you to check out the Hortilux Daylight Blue MH bulbs, they put out more blue AND more red than their SUper HPS, and although the lumens are reduced, lowering your hood about 3 inches totally makes up for that. Better, frostier buds in my experience.

My personal experience (not gonna repeat hearsay, theres plenty of that allready). I've used a futurebrite 600W digi ballast on a Sunleaves HPS & a 1Kw mag ballast on Hortilux Eye "Regular" HPS bulb & currently 1Kw mag on a generic 1Kw Hortilux clone bulb. I've never had any exploding bulbs, flicker, or any other issues period (so far).

The generic bulb is visually IDENTICAL to the hortilux, the only difference is the placement of the resistor and the little white round shield inside (minor stuff). The output spectrum chart on the generic's box is identical to the Hortilux, and I believe it to actually be the same based on my observations.

What you need to do is make your self a spectrascope. Google it. All u need is a digital camera, and old CD, and a small box. That'll give u a true idea of the actual spectrum. You can see the effect just by holding the CD and manipulating it; and I am currently making my own now.

Quantum + hortilux eyes = no blown bulbs for me. Even on a flip, I've never blown a bulb.

So is it the lumen output or the spectrum output that makes the Eye Hortilux the better bulb?

The thing of is that lumens are a measurement of the power of light as perceived by the human eye, not by plants. Plants absorb photons.

Overgrow used to have a great chart with the par watts of each manufacturer.I do remember the 1K hortilux was 535 par watts higher than all the others except for the 1K agrosun MH which was 6 hundred something

 

[crippled1]

And now I know why Hortilux is the favorite of so many, it puts out the most par watts period. Here's your chart...

I have experimented with plantstar; but I think im going to stick with agromax the initial lumen output is better and apparently the percentage of the blue spectrum is 10 higher as well.

Warning....
Chart wrong!
According to Hortilux and Sunmaster, their best 1000w bulbs have less than 400 PAR watts.

I don't know where this par watt info on Hortilux is coming from, I spoke with someone from Eye today and was told that they do not publish any lamp output data other than lumens.

Thats a good question then,although thats the same information it was in chart form on OG.Looks like someone may have made something up

I've been using a Hortilux Eye 1000HPS for my last couple of flowers, I had some concerns that it may be starting to lose spectrum if anything because my yield dropped a bit running the same recipe on the same strain at my last harvest...I had some other issues with too many plants in my flower room that made me second guess that assumption though. I do remember being more blinded walking in to flower when I first got the bulb though...a case of them (6) can be had on ebay for $400 with shipping, that's a lot less than what my hydro shop charges and makes the price a hellofa lot more palatable...I have a generic 450 HPS I used to flower under and an agrosun MH I also used to combine with the lil HPS before I got my 1000, I veg under those now, starting under CFL, moving to MH then finally the lil HPS before flower.
I don't mean to ramble but...I like the Hortilux bulb because you know what you're going to get, a quality bulb that is going to work. That and my mentor in this thing swears by them and that alone works for me.

I haven't used any grow specific hps lamps so I really can't comment from experience. What I really don't get is how many comments I read about changing lamps after 1 or 2 grows with similar comments to the above, no facts just taking it as gospel that they need changing.

On the right side are charts of lumen maintenance and mortality.

If I still have 80% lumen maintenance at half life (14000 hours) then I should get about 20 grows in by the time i've lost 20% of my initial output. 12hrs X 60 days is only 720 hours of use per flower cycle.

Of course that chart wouldn't apply to every bulb being talked about here but still... 10 grows would still be pretty conservative, no? I'm not ripping, just saying you could save some bucks.
