Producing LED Grow Lights Since 2007

4 years may not sound like a long time, but Lighthouse Hydro was one of the original three companies to have a dedicated production line of LED grow lights. They opened their factory in 2007 and now produce more LED Grow lights monthly than any other company in the world. What this means for the consumer is more experience and a trusted name.

American Distribution & Warranty

If they honor their own warranty, most online sellers make YOU responsible for the cost of shipping a failed LED back to China for repairs! In addition, repair and shipping times are usually 3+ weeks before you get your light back. Lighthouse Hydro’s distribution is located in the USA, and the warranty is fully covered by Gotham Hydroponics. If anything goes wrong in the first 30 days we pay for shipping and will ship you a replacement light BEFORE we get the failed unit back from you! Now that’s customer service!

Actual Manufacturer - Not Just An Importer

Lighthouse Hydro is a US company that has their own factory (Lighthouse Shangkong LTD) in China. No other seller we know about actually operates their own factory. While many LEDs may look similar, only Lighthouse has control over the components and care of construction. By having such a vested interest in the LED grow light industry and manufacturing process, Lighthouse is able to produce a high quality product at an excellent price.

No false Claims - No BS Guarantee

Over the last 4 years the LED grow light industry has had an amazing number of false claims from manufacturers and sellers. Be wary of LEDs that have promises that are "too good to be true". Many LEDs claim to cover far too many square feet, or have useless light spectrums (green, orange, etc). Lighthouse Hydro gives you exactly what you pay for - A great light at a great price. Call us to find out and we’ll tell you exactly the coverage, performance characteristics and pros and cons of any LED grow light solution. 845-504-5723

Cornell Developed Grow Spectrum & Beam Angle

Lighthouse Hydro created the world’s first 6 spectrum grow light. In the era of 2 band and 3 band LED’s Lighthouse Hydro pioneered the development and research into the effectiveness of additional wavelength and their positive effects on growing. While many others try and duplicate, none have done the research. Companies selling 8 band, 10 band, 12 band, including green and yellow LED’s, are fooling the customer into a "more is better" situation. This couldn’t be farther from the truth. Lighthouse Hydro uses the bands and the ratios that it does specifically because they have been proven to work. If a wavelength is not in a Lighthouse Hydro LEDs, there is a good reason why not. Typically extra wavelengths result in wasted light, energy, and electricity. Lights that use all 60deg LED’s are too focused and do not cover enough space to be effective. Lights that use all 120deg LED’s do not have the focused beams that make the flowers “pop”. A combination of 60, 90 and 120 degree LED’s are used in Lighthouse lights to maximize coverage while giving the focused light intensity that growers enjoy.

LED Grow Light 101

What's the deal with 2w and 3w LEDs? Are they better?

In terms of actual PAR (Photosynthetic Active Radiation) output, the 2w and 3w LEDs produce more usable light when compared with the 1w LEDs. This also means that they will penetrate better. That said, in terms of efficiency the 1w chips are more efficient in Watts / PAR Flux. Overall, the 2w and 3w chips are incredibly bright and allow you to get the additional boost of more power with a lower initial cost.

Why are you the best company to order this from?

With over 7000 satisfied customers and a 99.9% Positive Feedback rating, we pride ourselves on customer service and providing the highest quality Hydroponic equipment. Read about us in the Forums. Our customers love us! We do not cut corners and never make claims that are not legitimate (No... A 90w LED will not replace a 400w HPS). Just give us a call and decide for yourself. We love LEDs, but we also sell HPS, MH, T5, and CFL. We know the advantages and disadvantages of all lighting products, and never make claims that are not 100% valid and true.

Why do some of the LEDs seem dark or broken?

This LED Grow Light has 2 LEDs that may seem dim or not to be working at all. This is not the case - These individual LED diodes are emitting light in the InfraRed (IR) and Ultraviolet (UV) spectrums. This light is outside of the light spectrum that the human eye can see, and is used because of the beneficial properties for plant growth. Don't panic, this is by design. (These LEDs are typically found in the center of the light).

Why buy from a USA seller?

Buyer beware - Buy from China and wait up to 5 weeks for shipping. If the light is defective or damaged in transit, you must pay international shipping fees to ship back to China to claim warranty (if any). Additionally, many Ebay sellers are not experienced with grow light technology and advertise one thing, then sell you something completely different. Inferior LED chips, exaggerated coverage area, etc. Do your research before you buy.

Never buy from any company you can't talk to - 845-504-5723

We are not just an Internet company selling products we do not know anything about. We are a brick and mortar Hydro distributor, with over 15 years of hands on experience in the industry. Call us with any questions, big or small. We're here to help you make the best decision.

How is this different than your 6 band HO model and why are you using these bands?

More bands does not mean a better light. The light spectrum used in this Lighthouse Hydro LED contains the most efficient and proven wavelengths for flowering. For over 4 years, Lighthouse has refined the wavelengths of their LEDs. The 50W UV model has a majority of LEDs in the 660nm, 630nm range which is perfect for flowering. This light will work for VEG also, but if you are looking for a VEG/Clone light only then we would suggest an HO (High Output) LED (available in 90W, 180W, 240W, 500W), which have a higher concentration of white LEDs.

I live in Europe, will this light work here?

Worldwide voltage (90v-240v) is standard on all our LED lights. Customers in the UK will receive a UK power cord. Customers in Europe will receive an EU power cord. Customers in Australia will receive an AU power cord. If you are still concerned about power compatibility in your specific country, please call or email us.

How Many Plants will this light cover?

We do not exaggerate any claims. Coverage is limited by the physical size of the unit. Our suggested coverage for this light is about 2 Square Feet (1.5' x 1,.5'). Any LED light this size claiming to cover more area is a gross exaggeration by the seller, and an injustice to the buyer.

How does this light compare with HID lighting performance?

We sell HID lighting too, so there is no use in us claiming anything that is not 100% true. LED lights are more money up front, but you save about 50% on the electrical consumption of the light, cooling costs (very expensive in the summer) and annual bulb replacement. You can look forward to paying back the cost of the light in electricity savings over about 12 months of use. The most common error made when using LEDs is that people do not use enough of them. Follow the guidelines for recommended coverage area, and your LEDs will impress you with their yield. The much reduced heat output of LEDs when compared with HPS/MH bulbs also substantially reduces the risk of a fire hazard, especially in an enclosed space.

Does this light put off much heat?

LEDs are the most efficient lights in existence today. They produce so little heat; you can actually let the plant touch the light (although it's not recommended - as you will reduce the size of your growing area). Any heat produced by the unit is absorbed by the heat sink and disippated by the fans in the rear of the light.

What makes this LED different?

Lighthouse Hydro uses quality components, better LED diodes, and is a reliable company. All together, this produces an LED grow light that outshines and outlasts the competition. With more lights sold than any other LED manufacturer, Lighthouse Hydro is the name to trust. This is the only LED we sell in our storefront because it is the only one that has proven its success.

The Truth about Wavelengths

Traditionally, successful indoor hydroponic lighting solutions employed powerful High Intensity Discharge (HID) lights in order to simulate the intensity and required wavelengths for Photosynthesis. It is an adequate solution but a very inefficient one. Even the highest quality High Pressure Sodium bulb produces only 30% of usable wavelengths for photosynthesis, with 70% of the light completely wasted. This loss can be measured by specialty scientific instruments and advanced light spectrum analysis devices. Traditional HID lighting systems consume more power, produce an inefficient spectrum, and produce significant heat. These factors contribute to a very high operational cost and the need to address cooling solutions which can come with additional energy requirements of their own.

LEDs have existed for almost 50 years, but until recently, they lacked the light output and energy efficiency necessary to make them a viable alternative to traditional lighting solutions. Since 2008 the lumen output per watt of LEDs has doubled, and the best LEDs are now on par with HID lights in terms of lumens/watt with one exception, they are far more efficient.

Based on research done by scientists at Cornell University and other horticultural centers, Lighthouse Hydro has developed LED lighting products that optimize the usable light wavelengths absorbed by your plants. Neither HPS nor MH bulbs provide significant light output below the 580nm wavelength. This means that one of the largest portions of the light spectrum used by plants (420-455nm) is not supplied by either HID product. Additionally, the majority of HID output is in the green-yellow spectrum which is not only reflected by plants but also barely used in Photosynthetic reactions. The most important wavelengths for plant growth and flowering is found at the 420nm, 450nm, 630nm, and 660nm wavelengths. Red is more important for flowering and yields, and blue more important for node intervals & faster growth and absorption. We deliver these wavelengths, scientifically balanced for maximum efficiency. What once was 70% of light wasted is now light harvested. Lighthouse Hydro LEDs use a optimized blend of individual 60 degree, 90 degree, and 120 degree LED chips. In the configuration Lighthouse Hydro has designed, light coverage for the grow area is maximized and light penetration is increased when compared to lights using a single spread angle LED light.

Not all light is created equally. And neither are LED lights! At least not as far as plants are concerned. HPS, MH and T5 bulbs produce a spectrum that is fixed and based on the filament or phosphors in the bulb. Even the industry's best bulbs are only 32% efficient.

The above graph is the output of one of the leading HPS bulbs in the market. As you can see the majority of light emitted is in the yellow and green spectrum. These colors are NOT used by plants (hence the reason the leaves are colored green, they reflect it!)

Take a look at the graph below, this is the spectrum that the plants actually USE!
This is commonly referred to as the "Photosynthetic Action Spectrum".

Lighthouse Hydro UV LED lights use a specific ratio of individual LEDs to maximize the vegetative growth and flowering production of your plants. With a greater percentage of individual LEDs in the red spectrum, and the added Ultraviolet spectrum to signal day and night light cycles that naturally occur in nature, use of the UV light will result in faster flowering times and greater yield for your plants.

The graphs speak for themselves. Neither HPS nor MH provide much lumen output under 580nm. This means that the largest portion of lights used by plants 420nm-455nm is not supplied by either light solution. The peak lumen output is 580nm, 595nm & 615nm. As you can see, that translates into a loss of about 70% efficiency when overlaid with the light used by growing plants. Thus, a 40,000 400W HPS bulb translates into 12000 actual usable lumens. These charts are available from the HID bulb manufacturers and widely distributed, touting that they are closest to the natural light output of the sun. The most important thing is, plant's don't use all the light from the sun, they flourish when very specifically tailored wavelengths are used.

The final analysis is that the most successful growth is found at 420nm, 450nm, 630nm and 660nm wavelengths. Red is slightly more important for flowering but blue produces faster growth and absorption. It is also important for plants to get more 630nm-660nm wavelengths because it is reported that those wavelengths determine leaf diameter. Larger leaves will make a larger plant. And who doesn't love a big tomato plant! Larger leaves lead to larger surface area for further absorption.
