Do LEDs use less power than CFLs ?

I was thinking about getting some LEDs and wanted to know if they are as good as or better than HPS lights and if they use less power than CFLs

LEDs are much higher efficiency than *any* other light.

yes some led could be better then hps . but they cost 1000 and up . it only takes about 2 years to take advantage of the led power savings . now the big question is . are there any of those 60 dollar ebay led lights better then cfl then we would have game on .

But LED may cost more. A solid quality hps is also fine for using and cheaper.

LEDS are cheaper too run, less heat, hell i grow in a closet with no exhaust fans or aircon, try do that with CFL'S or HPS, my 300 watt CFL was too hot for the closet but my 300 watt LED is fine in their, LEDS are the way without aircon

I just find something online, hope them will help.

MH / HPS Combo (HID Grow Lights)

Pros

• Grow many plants indoors
  
  
• Very easy to maintain
  
  
• Comes in big and small sizes to fit the need of many grow spaces. Learn if your grow space is big enough to use MH/HPS lights
  
  
• HIDs are efficient grow lights for cannabis; MH/HPS tends to produce the bigger yields than other grow lights considering the amount of electricity used
  
  
• The golden standard for growing cannabis indoors - HIDs are the most tried-and-tested grow lights, having been used for growing cannabis for decades
  
  
• Know what to expect - many people find HIDs to be the most intuitive grow light, and there are lots of straightforward grow guides for growing cannabis with MH/HPS grow lights
  

Cons

• These bulbs cannot be plugged into a regular light socket; they need a special hood and ballast (usually sold together) - Teach Me More: http://www.growweedeasy.com/hps-grow-lights-setup
  
  
• Like any other high-wattage grow light, bigger HID grow lights often need an exhuast system to vent out heat - Learn how to make a cheap, stealthy exhaust for your MH/HPS lights: http://www.growweedeasy.com/hps-exhaust
  
  
• Can be expensive to get the grow lights & set up the grow area
  

If you have a bit of money to get started, a grow space or closet that no one will see, and the willingness to put a little more time and effort into setting up, than HPS (High Pressure Sodium) lights, or a combination of Metal Halide and HPS lights, are your best choice.

Both MH and HPS lights can be used for the whole grow cycle and work well. But you will get even better results when you use both types of HID lights - MH and HPS.

Use your Metal Halide bulb for the vegetative stage, and the HPS bulb for the flowering stage. This combination of grow lights closely mimics the sun's natural light during the different seasons, and is the most tried-and-tested grow light combination for growing marijuana. Many modern ballasts come with the ability to support both kinds of bulbs.

LED Grow Lights

Pros

• Many growers report LEDs produce greater resin production and better taste/smell than other grow lights. The type of light produced by LEDs may cause cannabis to produce more trichomes (glitter) and terpenoids (smell) in the flowering stage.
  
  
• LED grow lights are efficient - they produce a lot of light for the amount of electricity used
  
  
• LED grow lights continue to get better for growing cannabis - LEDs are relatively new. and cannabis yields are going up while prices are coming down
  
  
• Most LEDs come with a built-in fan to disperse heat up and away from the plants
  
  
• LEDs can be plugged directly into the wall - no need for a separate ballast
  

Cons

• High initial cost
  
  
• Don't believe all the crazy marketing hype about LEDs - if a claim sounds too good to be true, it probably is! Some unscrupulous retailers are trying to make a quick buck by selling poorly designed or untested LEDs to unsuspecting growers, often making outrageous claims.
  
  
• Lower yields/watt than an HPS grow light
  
  
• LEDs, like all grow lights, produce heat. With bigger models (using lots of LED chips) you will need to vent hot air outside, even if the LED has a built-in fan.
  
  
• Poorly designed LEDs can cause bleaching, crispy leaves, spots and other cannabis growing problems. This can also happen if LEDs are kept too close to your plants. Always buy LEDs from a trusted source that has tested their models on real cannabis plants! Also make sure the seller tells you how far to keep the LEDs from the tops of your plants.
  

For the advanced grower who wants to use the most cutting edge technology while achieving the highest quality buds possible, LED grow lights may be the best choice for your next cannabis grow.

Yes. And CFLs yield much less, and while LEDs are initially the most expensive part of your grow that you'll buy, it's got a good return if you get quality ones.

LEDs typically use 60% of their listed wattage. Like, my 240w veg uses about 144 actual watts. My 500w will use approximately 300w. They also have better penetration and effectiveness on the yield.
