LED grow lights for sale in the US are offered in many different levels of quality and performance. Before you begin looking for LED grow lights for sale try to pick which brand of LED is best for your garden. Cheap LED grow lights are commonly made in China with Chinese parts and sold under names made to seem strong and powerful. Names are a terrible way to determine which LED grow light to buy since many are simply misleading.
LED Grow Lights for Sale – Made in the USA
If you see an LED grow light for sale with the title “made in the USA” make sure you understand that many companies will simply lie (or mislead you) about this especially those who are new without much of a reputation (fly-by-night companies).
If the LED grow light for sale is made with all 3w LEDs make sure to ask for pictures or descriptions of there heat sinks and look for wattages not to exceed 2w each. Heat sinks using these high powered 3w chips should always include tall fins to disperse heat quickly without reducing the life of the LEDs prematurely. High heat is the enemy of LEDs and causes them to die much faster than the company will lead you to believe. If heat is not a priority of the company with the LED grow light for sale then you should look elsewhere. Those who claim extremely high wattage (higher than 2w per 3w LED) being better simply leave out the fact that the high heat produced will cause the lights to fail much quicker than they should.
LED Grow Lights for Sale with High Junction Temperature = Shorter LED Life
LEDs do not fail all at once unless there is some type of driver or connection problem. LEDs that are driven too high will immediately begin to start fading and the point which they cross the 70% of original power will be much faster than sold to you.
Look for a brand such as Advanced LED that drives their LEDs at the highest power possible while still maintaining the life of the LED. Choose an LED grow light for sale that features real 3w LEDs using the most advanced secondary optics available today and at least a 90 day guarantee with no hassles.
If you want to save all that time, you can rest assured the best selling 3w LED grow lights in the USA are made by Advanced LED. Professional and hobby growers choose Advanced LED due to low cost per watt, high performance and extremely high levels of customer service. Advanced LED even offers a 24 hour warranty service guarantee and a 90 day return policy to guarantee your satisfaction for all the LED grow lights sold.
Long-Run Cost Reduction with LED Lighting for an Indoor Garden – dahlberg light and power
One of the biggest cost considerations for indoor gardening is power consumption. The energy requirements of an indoor garden can vary widely depending on a several factors, from the scale of the indoor facility being used to the type of plants being grown to whether the horticulture is hydroponic or soil-based. Hydroponic growing systems need expensive irrigation and pump setups that can drive up costs, but these costs are usually mitigated by increased efficiency and bigger yields, which is why so many indoor gardeners are enthusiastic about hydroponics.
Other factors that influence the energy requirements of indoor gardening are ventilation and lighting. Growing plants indoors requires a suitable light source that replicates as closely as possible the intensity and spectral qualities of sunlight, and proper ventilation is necessary to sustain healthy plant growth. The choice of lighting types used in an indoor garden can affect the type and level of ventilation system required, which in turn can have a direct effect on the energy efficiency of the entire indoor garden.
The traditional lighting method for indoor growing has been the use of High Intensity Discharge (HID) grow lights, such as High Pressure Sodium or Metal Halide lamps. HID grow lamps work by energising gas vapour inside a sealed lamp with an electric current. Due to the negative resistance that is a characteristic of the gases used in these types of lamps electrical ballasts are used to regulate and limit the current, which might otherwise rise to destructive levels.
While these types of lighting systems work quite well for indoors growing by providing light of the intensity and spectral quality necessary, they have several of drawbacks that heavily affect the bottom-line cost of operating an indoor garden. HID grow light systems are heavy, hard to mount, use excessive amounts of power, often require specialised wiring and create large amounts of waste heat. This waste heat issue becomes a cost-consideration because a higher-capacity ventilation system has to be used to deal with the excess heat and draw it off to ensure a proper growing environment within the garden.
This is why the development and evolution of Light Emitting Diode (LED) grow light technology over the past decade has indoor gardeners as enthusiastic about LEDs as they are about hydroponics. LED systems not only produce growing light of comparable intensity using a fraction of the energy required by HIDs, they also have superior spectral bandwidth qualities to optimise growth at all stages of the plant life cycle. LED grow light systems do not require the use of heavy and bulky ballasts or reflectors. They are lightweight and need no special wiring, so they are easy to mount and move. Moreover, LED grow lights do not create the excessive waste heat of conventional HID systems, so further cost and energy savings can be realised through a scaled-back ventilation system or none at all.
It makes sense to install an LED grow light system in a new garden or replace an HID system in an existing garden when these energy-usage cost savings are taken into account.
10w LED grow lights… Really? – dahlberg light and power
10w LED Grow Lights – Are they Better or Just a Gimmick?
We covered 5w LED grow lights in a previous post and discussed the truth behind this type of LED grow light, but now it’s time to cover LED grow lights with 10w LEDs. 10w LEDs are made by many different types of companies around the world for industry such as parking, tunnels and other commercial fixtures.
10w Single Chip vs 10w Array
Don’t buy into the myth that a single chip LED is more powerful or more potent than an array. Although this can be true sometimes, it is definately not the rule. Watt for watt many LED clusters provide more Lumens and more PAR than their single chip counterparts, and come with many other benefits. Although there are very few single chip 10w LEDs in the market they do exist, with 10w arrays being more available.
Wattage Per LED – What will last?
CREE makes a 10w LED that can be ran between 4.5w – 6w on the high side. Like 5w or even 3w LEDs for that matter 10w LED grow lights should never run at a full 10w each, even if the manufacturer has 10w as the maximum. The “maximum” provided by most major brands of LED chips is usually the “just before it fails” calculation and should usually be cut in half for the long term operating wattage of the LED.
Which is better? 3W, 5W, 10W or Higher LEDs?
This question will be asked by many growers over the next few years as technology grows and advances into the new age of LED. Although every company in the LED grow light field will have their own opinion that they promise to be the best, the answer is not cut and dry. At this time, 3w LED grow lights are dominating the market and will continue for quite some time but 5w will become more popular soon but there is one major factor we must consider: The number and wattage of each LED.
If you have 3 10w LEDs running at 5w each vs 10 3w LEDs running at 2w each, which is better? The answer is they will be very close to the same but the 3w will probably beat out the 10w because they have a 5w advantage is power and triple the number of emitters. Here is the formula for measuring any LED grow light against another:
Step 1. Confirm the LEDs are not being over driven: example: 10w@5w each, 5w@3w, 3w@2w. (correct watts)
Step 2. Multiply the # of LEDs by the wattage of each. (Actual wattage)
Step 3. Take the total cost per LED grow light and divide by the actual wattage. ($/w)
Step 4. Buy a Diamond Series LED grow lights. 🙂 Diamond Series LEDs use 3w LEDs, run at the correct wattage for long term use and have an industry leading $2.80 per actual watt of power. Many other companies charge over $5 per watt for the same quality and performance.
