If ya know, ya know
Are 600w hps being discontinued??

At 31 cents per KWH I dont no anyone using HID lights anymore cant give them away here.LEDs are not 100% more efficient, not yet.
They are 50% more at best if you have them on full blast.
Maybe some high end systems reach 100% but I haven't seen those at the avg grower tents.
HIDs will disappear at one point or another as it's a sun like light source, which is good for the people, bad for the ones making artificial lights such as LEDs and want to replace everything that's nature like to artificial like.
Stock em while you can, while it's cheap, while it's affordable, HID systems used to cost a fortune, they will again when everyone will miss what organic light can achieve.
It's already begining, don't say I didn't told you

Let us remember MMS saying he tried so many leds and finally gave up and made the 6K Bulb...
Hmmm arent LEDs supposed to be superior tech if I understand correctly...lol
It's artificial light, not natural, not in spectrum and not in the principles of anything near the sun.
Maybe that means something and maybe not, time will tell.
His 6k bulb in that price is def worth it, but durability will have to be checked.

An HID bulb is no more natural than a diode.
The fact that HIDs produce their light through ionization is irrelevant.
LEDs are far more efficient and have a more "natural" spectrum, to borrow a term.

Watts are watts bro, a 600 hid will take same electric like 600 led panel.
Irrelevant ?
Could be, who are we to know...
We just know it's different.
I prefer nature or as close to nature as I can, I'll leave the science to smart people, I trust the sun principles more, to each his own.
Btw again they are 50% more, not far more, but they are getting there indeed.

2.6+ umols/watt for a current top-shelf LED fixture
1.3 umols/watt for HID
Easy math.

I have two units, LED that is… HLG 600 rspec 600w quantum board style with 4 panels and a mars hydro FC-E 4800 480w bar style light both with dimmers. I like the wattage penetration of the Hlg but the bar style spread is very nice. I used HPS and mh in the long ago and glad I don’t have to now!

There's some comparisons online.
From what I remember the top end bulbs are 4 times the price than some of the new cheap ones , but only fractionally better .
Just Google it or search YouTube.

Watts are Watts but a 600 watt LED puts out more light than a thousand watt hps and less heat than a 300 watt hps. So if a guy had a tent with a 600 watt hps in it, he could run a 300 watt LED and have the same amount of light but half the electricity and run the exhaust fan less because of the less heat.

Watts are watts, each watt is 3.41 BTU of heat.
A 300w lamp (of any type), a 300w computer, a 300w television, etc., will generate the same amount of heat.
A 600w LED will produce exactly twice the heat of a 300W HID.
The distinction is that LEDs don't waste their wattage budget on IR heat, most all of LEDs output is in the visible range, hence their efficiency.

A 600w hid will pull the same electricity as a 600w led. The difference is, an hid will convert ~40 - 50% of that electricity, into heat, instead of light.

For sure. I get it. It's too much heat for me. Even in winter, but I'd prolly still just get a
It won't need to make heat, constant, like the light would.
That's just my preference though. To each his own.

The best bet is to buy cheap HID single bulbs (apollo ,ipower, etc) in bulk, and switch them out every 1-2 grows, so you maintain the highest output at all times. If you blow $60-100 on one "super special grow" bulb, its gonna depreciate just as fast as the cheap ones anyway, which cost like $20 these days.

Unless its the new ceramic HPS they quit making.. They probably last a little bit longer, and might be worth it for the extra cost.

Those are ppfd space measurements, not total output.
In total output of light systems, leds only make 50% more for each watt, 1w diode makes 240lm, a good hps will make 160-170lm for each watt, not 100% more, more like 50%.
That's the reason a 300w led cannot replace a 600w hid, it won't work, the led makes 60-70k lm, the hps 95k.
So a 400-500w led is more in the realm of 600 hid, not 300.
Wrong, a 600w led will make 110k lm, a 1000w hps will make 160-170k lm
Your numbers are off my friend.
As I said above, a 300w led cannot replace a 600w hid, maybe a 400w yes.

No, you're mistaken
The numbers I posted are empirical measurements taken with a Apogee ppfd meter and are not the theoretical gross output sphere measurements you may be referring to.
Nonetheless, lumens/watt is not the correct measurement to quantify useful light output for growing plants, ppfd is the measurement of interest.
These are taken from cocoforcannabis.com, Migro also posts independent light measurements with similar results.

I small fact you missed I can run 600 watts of led on a 5x5 an pull more weight compared to running 1000 watts of hid on that same 5x5? So that is a 40% saving on 31 cents per KWH I grew with Hids for 40 yrs Switched out a few yrs ago very happy never going back.

There is also the issue in turning the light; hps is omni directional and you lose a lot of light on cannopy thru reflectors
