They made a High pressure sodium equivalent as in the spectrum and only 250/400/600/1000watt dimmer settings plus overdrive.

Sometimes I'm not buying a car for the best mpg or top speed, maybe I want something in the garage for the weekend and a nostalgic trip down memory lane.

Would it be too much for some company to do a special run, you know something for that grower that already has every light and grows more than he can smoke and sell already.

Feel like something I might want!?!?
 
Oh, you still use HPS?😮 my first ever grow was with a 70 watt security light because I didn’t know where to by a proper grow light.😅I just wired a plug on to it. But that was so long ago I can’t even remember when? And I can’t really remember what hps did that leds don’t?

I hate electricity bills!😏 some people round here steel there electric but I’m not sure how to do that? I’m not sure if I’d want to either?

I had an led but went HPS this time. I can swap a lot they all work and for one light I don't feel anything on the monthly bills.

But yer I'd own an led hps spectrum light that emulated the old days.

Why not just buy a pet heater lamp to match all the wasted energy hps made in ir

Electric prices are ridiculous for me! My two little tents combined don’t use much more than 200w but I still notice a dent.

Guide on how to steal electricity -

Step 1 Aquire automatic rifles and rocket launchers.
Step 2 Goto your nearest dam
Step 3 Take over the dam trying to kill the least amount of workers and guards possible
Step 4 You now have several Lifetimes of the stuff

😅 ok. Well if I get killed in the process then you know what happened to me if I disappear

HPS produces very little IR it's under five percent last time I did sciencey hps stuff.

The sun produces a lot more per spectrum, LEDs a little less depends on brand and craze at present.

Why do they produce soo much heat then?
PAR (400–700 nm, plant-usable): ~25–35% of output

Infrared (700–2500 nm): ~40–50% of output

Other (UV + non-useful visible + losses): ~20%



Led produce around 5%

Because light is heat and all visible spectrums are of similar energy.

Yes as i said IR sooo buy a pet heater lamp they are ir and you can have a led that is like a hps.i guess for a 300w led you need 150w pet heater

The led doesn't match a sodium spectrum signature and the pet heater doesn't make it any closer to that.
 
Why dont you buy more than one led diode? Led come in all wavelenghts

Here is somr ai put out for 300w
1. White Base (total ~175 W)

6 × Samsung LM301B 3000K strips (e.g., Bridgelux EB Gen3, Samsung F-series, 50 cm @ ~25–30 W each)

2 × Bridgelux EB Gen3 2200K strips (50 cm @ ~12–15 W each)


(These run on aluminum bars or heatsinks, wired in series-parallel.)


---

2. Red Channels

Red 620–630 nm (Osram Oslon SSL or Luminus SST-20 Red, ~3 W each @ 700 mA)
→ Buy 7 pcs (~20 W total)

Deep Red 660 nm (Osram Oslon SSL 660, 3 W each)
→ Buy 15 pcs (~45 W total)

Far-Red 730 nm (Osram Oslon 730 nm, 3 W each)
→ Buy 7 pcs (~20 W total)



---

3. Near-IR

Mix of 850 nm + 940 nm diodes for radiant heat

Use Luminus SST-20-IR or Osram SFH series (~3–5 W each)
→ Buy 8–10 pcs total (~35 W)


(e.g., 5 pcs @ 850 nm + 5 pcs @ 940 nm for a balanced IR glow)


---

4. Blue (450 nm)

2 × Cree XPE2 Blue (3 W each) → ~6 W total



---
You have to diy because it not logical to make a lamp that gives less

I just wish I had a greenhouse tbh. I could let the sun do all the technical stuff for me.
