LED-HID equivalents...? IF ANY....

The more I read about LED's, the less I seem to understand....
I am used to knowing floor space and calculating how many watts would suit that area...
My 4 x 4 tent has 16sq ft so 600w is adequate and1000w is quite concentrated light.
If the lamp has a sky high lumen score - fantastic, a great bonus.

I also know that MH lamps emit blue light (4000-5500kelvin - good for VEGETATIVE GROWTH)
and HPS emit red/orange light (good for FLOWERING),
Duel Spec lamps are mostly red with a touh of blue....

WHA I DO NOT KNOW IS WHAT LED's ARE EQUIVALENT TO A 600w MH or a 1000w HPS....???

Are LED's available that can replace T5 cfl's...???

I just need an article that starts to explain these things....

Many thanks

A good place to start would be the sticky threads at the top of this forum.

I agree with Spiko above, reading is your best friend, in this situation.
I will say that in our little LED nerd community here, we consider Area 51 LED's to be the best bang for the buck.
I own one and they're fantastic.

Hiya NorthofEngland, I'm interested in this aswell...even thinking about starting a D.I.Y. project in NewYear...anyway Waffling...Not found much Info about this...did find this Thread though -

Apaches are too xpensive. i would go with A51 or inda gro around same cost to match a 600 hps.

600 watt hps set up quantum ballast, yield master hood, digilux bulb - $300 (homie price), inline fan and ducting - $225 = $525 just say $550 plus replacing bulbs every 10 months- $300 and plus triple electric costs. with hid almost always have to run a/c too. $175 a month in power. just for garden



2 a51 panels 330 watts $900 - lifetime warranty - electric costs $50 a month. no a/c needed. they don't put out anywhere near the heat of hid

inda gro 420 watts $800 - 10 year warranty - electric costs $60 a month

should pay for itself in electrical savings in about 6 1/2 months.

LED Lighting
--------------------------------

LED is the technology of the future. And since it's from the future, it costs a lot more. A LOT more. About 10x the price per watt as HID. It's also indisputably better at growing plants watt for watt than HID. It also emits more light per input energy unit than HID.

BUT. LED's worst enemy is its own supporters. They frequently claim things which are just not true. UFO sells a 90W fixture with only about 73W driving the the lights and says it's equivalent to a 400W HPS because of the PAR output. PAR output matters, but SO DOES LIGHT PENETRATION. High PAR wavelengths don't penetrate better than low PAR wavelengths. Therefore, you have to throw the same amount of light in the first place, and use the high PAR wavelength tweaking capability of LEDs to BOOST the output over an equivalent output lighting of HID.

I will say this: 400W of LED will destroy 400W of HID in any test. It's not even debatable; LED grows usually get >1g/W. On the other hand, it's EXTREMELY difficult to say what wattage of LED will match/beat what higher wattage of HID. Since the PAR activity of the two lights are so disparate, and the only way to improve penetration is to throw more light, you will pretty necessarily end up with a situation where one will be VERY difficult to directly equate to the other and figure out that 332W of LED = 400W of HPS or whatever it may be.

EDIT:

Hope this is of some help???? If I can Dig up any more Info I will Post.

Peace

& Happy Holidays

Hiya NorthofEngland, found some Info on the A51 that peeps seem to Rate..inc a Link to site..



SGS-160 LED Grow Light


Unit Size: 12" wide, 18" long, 2.75" thick


Power Source: 48x Cree XPG Outdoor White + 24x Cree XPE Red


Electrical Consumption: 120w Veg Mode; 155w Flowering Mode (actual draw -/+ 5w)
When we say 120w and 155w, these are the actual power that they will draw, not the maximum power the LEDs can be driven at. Maxed out this lamp would be pulling over 300w.


Coverage: Minimum 24" x 24" ; Maximum 36" x 36" ; Recommended 24" x 36"
We recommend that you try to stay close to 24"x36" as possible, 20"-24" above vegging plants operating at 120w, and then 18"-20" in flowering mode operating at 155w.


Cooling: Finned Aluminum Heat Sinks + (2) 120mm 73cfm/10dba ball bearing fans.
We sometimes get questions from people asking why we use fans, and not try to design a fanless lamp. Here are the reasons that we use fans: The fans in our lamps operate at 1w each, 2w total for fan power + 10% ac/dc conversion, meaning the fans consume 2.2w, though they are responsible for 30% better efficiency over using a larger heatsink and no fan. Long story short: Fans are just better than no fans.


Operating temperature: 77F - 86F / 25C - 30C (generally operates a few degrees higher than ambient temps) We recommend that you keep your grow room between 70°F and 77°F, not only because that's a good temperature for plants to grow in, it also keeps the temperature of the LEDs cool, thus making them more efficient. If your grow area is 73°F, that means that your LEDs will be operating at 78°F, or 25°C which is very close to optimal temps for the LED to operate at its most efficient.


80° Degree secondary Optics
We use an 80° degree lenses with this lamp because an LED without a lens spreads out the light far too much, so much that some light is being emitted practically sideways and will never make it to the plants, and a good portion of the light needs to travel further to the grow room walls, just to have to reflect and travel again to the plants, losing much intensity along the way. Lenses redirect all the light exactly where it needs to go.


Daisy Chain up to 6 Units
You should check to see what the maximum load is on your circuit breaker before connecting too many units. You do not need a special cord to daisy chain. The 1st unit plugs into the 2nd unit, 2nd into the 3rd etc... then the last unit plugs into the wall.


Universal Voltage 100-240v
Our grow lights will operate on any voltage from 100v-240v. You do not need any special drivers or cords to run on different voltages.


Retail Price: $545.00 + Free Worldwide Shipping


All orders going to a USA address will ship from Virginia, USA. Orders shipping to a Canadian or European address has the option of getting the light shipped from the USA, or Hong Kong.


Includes a Free Adjustable Ratchet Hanging Kit


Limited Lifetime Warranty



XGS-190 LED Grow Light


Unit Size: 12" wide, 18" long, 2.75" thick


Power Source: 72x Cree XTE Warm White 3750k XTEAWT-02-0000-00000BFF6


Electrical Consumption: 130w or 190w. These are the actual power that they will draw, not the maximum power the LEDs can be driven at. Maxed out this lamp would be pulling over 360w.


Coverage: Minimum 24" x 32" ; Maximum 39" x 39" ; Recommended 32" x 32"
We recommend that you try to stay close to 32"x32" as possible.


We recommend 30" above seedlings in 130w mode, 20"-30" above vegging plants in 130w mode, and then 20"-24" above flowering plants in 190w mode.


If your grow space is limited, you could always run the lamp seed to harvest on 130w mode. 14" to 18" above the plant tops is more than enough intensity and coverage for flowering plants in a full 24"x36" grow tent. You could use this lamp in as small as a 24"x24" grow area with as little as 48" of height, based on 14" from the canopy and 18" tall plants and 12" tall growing container.


We suggest to look at our Umole charts on the Specs and Datasheets page, and position your XGS-190 above your plants according to those charts.


Seedlings need 200-400 Umol'/s, vegging plants need 300-500 Umol'/s and flowering plants need 500-800 Umol'/s in its core area and 150+ on the edges. Anything more than 800-1000 Umol'/s is not necessary as it will not add to yield, size, density or potency. Some plants will show signs of damage even at some levels below 800 Umol'/s.


Cooling: Finned Aluminum Heat Sinks + (2) 120mm 73cfm/10dba ball bearing fans.
We sometimes get questions from people asking why we use fans, and not try to design a fanless lamp.

We use a 95° degree lenses with this lamp because an LED without a lens spreads out the light far too much, so much that some light is being emitted practically sideways and will never make it to the plants, and a good portion of the light needs to travel further to the grow room walls, just to have to reflect and travel again to the plants, losing much intensity along the way.
