Hortilux Ceramic HPS - Total trash?

[homebrewer]

He was wrong. These go in normal hoods according to hortilux if you want to and they run best on the hortilux gold eballast. I'm betting they run on any 600w ballast though but the gold ballast is actually fairly cheap so who cares.

What week are these in?
Where you using 1k hps before these lights or something smaller?

Week 6 of flower two weeks of veg with the 315 CMH and now 3 600 watt ceramic hps

Well I'd never put any lamp in a sealed unvented hood. Dont think any of them are rated for that....

I've heard that even vented hoods can mess with the operating temps of some bulbs which can cause them to run out of spec. Don't ask me where I heard/read that, it's been years and never a concern with the equipment that I use.

The ceramic mh holds its own I’m impressed with this as well the phenotype I choose was a short bushy plant I’m going 4 weeks with these ones week 2 now Sensi Seeds shiva Skunk regular seeds

 

[The high chief]

I’ve been at this for 23 years now and I’ve never had a skunk smell like this the best way to describe it is gross

 

[thccbdhealth]

What i dont quite get looking at the c-hps 600w the lumen output is at 32 500
and my philips 315cmh is 31000
and i couldn't find the lumen output of the hortilux cmh.

 

[pinner420]

Is this light rated for vertical?

 

[The high chief]

Lumens are a term people use to describe how bright a light is a plant doesn’t see it that way they see the ultra violet colours the reds and yellows and greens and blues and purples

 

[thccbdhealth]

SO in your opinion

Is the 600w c-hps @ 32500 lumens
out proforming
Your 600w supers hps @ 88000 lumens?

Lumens are a term people use to describe how bright a light is a plant doesn’t see it that way they see the ultra violet colours the reds and yellows and greens and blues and purples

Lumens represents total power output weighted by a luminosity function.

In order for the 54lm/W of CHPS to compare to the output of a 600W super HPS with 147lm/W, the ceramic HPS would have to have a luminous efficacy of radiation (LER) of about 154lm/W. I haven't calculated/estimated LER for ceramic HPS yet, but I really doubt it's that low. It's more likely around 250lm/W which would put its efficiency around 21%.

Straight up, super HPS emits more light per watt, not just in lumens, but in W/W..

 

[churchhaze]

If it did have a LER of 154lm/W, that would imply the spectrum is terrible.

 

[churchhaze]

As it turns out, I've actually digitized ceramic HPS in the past. Looks like I got LER = 221lm/W

 

[churchhaze]

This is what I have for a DE.



I just can't understand why anyone would pick ceramic HPS over good old HPS. Even % PAR is better.

Their test shows very close useful spectral watts. Even if performance is same I would rather have the natural light to work under.

I wonder if I can keep it at 18” in my blockbuster air cooled reflectors like the super hps 600w?

Useful spectral watts? you mean all the light between 400nm and 700nm? (PAR)?

You're starting to sound like a combination of LED fanboys and T5 denialists. Also, how is being "more natural" important?"

Here's my digitization i did of a T5. It looks like even T5 beats ceramic HPS (on paper).

"look how great HPS is.. now get me a better spectrum because somehow HPS is terrible now"

No need for insults. I used the language in the test I posted.

It’s the high peak that makes hps work so well. And the chps looks like it has a similar high peak. And the wider spectrum should promote better health and maybe cannabanoid and terpene production.

I like the natural light to better see the color of the plants. Nicer to work under too. I had hoped that I would be satisfied with the Phillips 315 cmh but it was not powerful enough for my method.

I am investigating this new bulb same as you. I still use Hortilux super hps for flowering.

Well it will be nice to see what you can do in terms of yield. You know what my guess is already. Sorry to be insulting, but that type of language is marketing language most commonly used by blurple salesmen on amazon. " stop wasting power on those useless wavelengths and focus on these "better" wavelengths". None of it has proven better results. HPS has 2 things going on for it. It's efficient, and it has as great spectrum for growing tall flowering plants. Could the spectrum be a bit better? theoretically yes. Do you think you're actually making it better? You're probably making spectrum worse!

Well I can get about 20-24 oz from 4 plants under a 600super hps and I got 15 oz from 3 in a test run under a 315 cmh 3100k.

That’s more per watt with the fuller spectrum of the 315.

The better spectrum also kept the plants greener through the cycle.

However. The plants stayed a bit too compact and grew a bit too leafy compared to the hps.

My mind is open to a better flowering spectrum. For now 2 600 hps to 1 315 cmh has given me the best results so far.

hmm, read this thread from beginning to end... all these "experts" weighing in with their personal opinions, lots of talk of spectrum intensity, lumens/w.... high and low outputs in certain light ranges.

tf you all on? has everyone in this thread had nothing but smoke blown up their ass to help confirm their personal beliefs (most of which are total fucking bs btw...) in terms of legitimate output, quality of flower, potency and yield. fact of the matter is, there are only 2 values that should be considered. lumens/sqft, and CRI... its amazing how a thread about nothing but lighting... 5 pages in, and not one person has touched on the subject of CRI ? tf is wrong with all of you. simply put, even though its old tech, it has Not been surpassed by any other style of lighting. Ceramic metal halide is hands down without question, the absolute best. far from cost effective though, LED, HPS, MH, Induction... all fall short to CMH. CMH has a CRI (with quality bulb) of ~95%+. 2nd closest will be induction, followed by HPS, and then LED and finally MH. argue, bicker, bitch, complain, attack me personally. none of this will change the facts. when it comes to best of the best and concentration on quality of product, CMH simply cannot be beat. not going to argue, discuss, nor respond... believe differently and want to dispute? theres this amazing thing referred to as search engines... do some research and learn something. as to the rest of you claiming this or this is the best.... you have no idea what youre talking about. and function on purely on ego. Prove me wrong. With verifiable facts. until then.... CMH is the goto in terms of yield and quality. HPS is best in terms of value /$.... LED isnt far behind hps but has a very high initial buy in price. Induction is on par but wildly over priced... MH will beat out HPS on potency but never match in terms of yield. Realitys a bitch.
