Led Grow Light Par Vs Hps Par

Discussion in 'Grow Room Design/Setup' started by DanGrow, Jun 12, 2014.

  1. toy lights, you need a small truck load of them to grow in any decent sized space.
     
  2. The high initial cost, rapid obsolescence, high failure rate within first 2 years.. definitely not a technology to invest any significant amount money into yet imo.

    Unless you're geeking out, your money is better spent on HPS lighting.

  3.  
      For LED :
    1. Screw into a socket or plugin to an outlet                                        
    2. Around 50,000 hour lifespan
    3. Lights are slightly warm to the touch
    4. Optimized spectrum for photosynthesis
    5. Uses up to 30% less energy than HPS
    6. Lights are silent when on
    7. Creates a concentrated lighted area
    8. Stealth growing with no thermal footprint
    9. Contains no toxic substances
    10. Instant on
    11. LED technology is improving everyday
    12. Durable       
    HPS Grow light : 
     
     
    For HPS :
    1. Requires an expensive ballast
    2. Around 20,000 hour lifespan
    3. Lights are very hot
    4. Emits wavelengths not needed for plants
    5. Uses more energy than LED
    6. Creates buzzing and humming noises
    7. Requires a reflector
    8. Leaves a thermal footprint
    9. Contains mercury
    10. Have a warm up period
    11. HPS technology is stagnant
     
  4. Most of the above points are rather silly.

    Yield per square foot will suffer ising LED as opposed to HPS.

    Add high costs and small coverage areas and it's just silly to downgrade to LED.

    You made a pro/con list consisting of only pros for LED and only cons for HID..and alot of the shit you said about HPS is just plain retarded..like emits wavelengths not needed for plants, contains mercury, buzzing or humming noises. 
     
    Flourescent bulbs contain mercury too, but it's not like the mercury is dripping onto your plants or into the air..lol
     
    Also expensive ballast? A decent LED light costs way more than an HID setup..so your price comparison is also retarded
     
    LED does have its benefits..practically no heat and better on electricity but the fact remains that HPS is going to give you a better yield than LED will.
     
  6. Hortilux hps bulbs can be tossed in the trash. No mercury issues.

    Agreed the list is beyond silly.

  7. Looks good , any advice about it ?

    640 mA???? That's barely over half a watt... I'm guessing the seller doesn't understand.... Ok 3 watt diodes times 50.... That's 150w MAX! And don't forget LEDs actually are ran at less wattage than what they are advertised to prevent heat and premature burnout. I would guess it's closer to 80 watts.

    LEDs vs HPS, by marketing numbers (like this "600w") yeah the led doesn't stand a snowballs chance in hell for comparison. If you run a Mars II 1200 (546 actual watts) yeah it can probably compete with 400 maybe 600 HPS. If you go with white spectrum 1,000 watt LEDs like me....I've seen other people pull more than a 1k HPS.

    I don't have the experience to get full potential from the lights that's for damn sure, but my buds are over a week more mature than they were under my old 540w led. They are much bigger, more dense, and more sticky.

    One good thing about HPS is bang for the buck. But if heat is an issue, and you want comparable harvests... You need to invest in quality.

    I've seen people pull more than 1g per watt with the simple Cree LED bulbs (9w and 9.5w) Just do your research, there are plenty of excellent LED lights you can get!

    I am using an Area 51 LED light coupled with Cree bulbs. You can get even better results making your own from good Cree COBs.
     
  10.  
    For the cheap ebay type LED I would agree, however there are a few companies with GREAT warranty and quality of product.  The truth is LED will replace HPS soon.  It already is to be honest.
     
  11. LED cannot be independently air-cooled without compromising odor control, all your heat must pass through either a filter or an air conditioner.
     
    If it wasn't for that tiny detail I'd have bought one already, but I have no problem running my 1kw HID with air-cooling only. I'm pretty sure that if I wanted 1kw HID yields out of an LED that I'd have to run an a/c to handle the heat, thus defeating any efficiency gained.
     
    PAR vs PAR may be one thing (which hasn't really been addressed in this thread), but it doesn't take into account the total cost/benefit of setting up an LED grow. Air-cooling is a huge cost advantage allowing for bigger yields with HID that LED just doesn't have yet.
     
    Sure, LED's are fucking cool as hell and I'd love to have an opportunity to play with them, but I still think of them as a rich kid's toy. Not something I'd invest in if I'm trying to get the most bang for my buck.
     
  12. You have a point I agree with. My led setup does put off some heat and I wish I could run a small fan to cool it like a cool tube. However how many serious LEDs are there on the market (serious being 800 actual watts or more). I mentioned this just the other day and a grower with the same light as me is working on a hood. As led companies become serious and give up on the "same as 1000w HPS but only uses 150w" bullshit, LEDs will come stock with Inline cooling. It's only a matter of time.

    If (supposedly) better quality meds is only for rich boys....

  13. People like to compare specs on paper between lights, however, I've yet to see any weed grown under an LED that's comparable to that grown under an HPS.  It's not for lack of trying.  I tried several LED grows, and they were fine, but my HPS grows are legendary!
     
  14. What's your LED chip brand ? What's your LED chip board Temperature ??? What's your Power supply's  working efficiency???
