Indoor LED Grow lights for a 4 foot tall container Lemon Tree?

Posted by infomofo 6 (My Page) on

I have a Meyer Lemon Tree that's about 4 feet tall and in a container. I move it in doors every winter. Last winter was very rough, and I am worried that the home depot plant lights I was using were not sufficient. The plant has recovered beautifully over the summer months, but I would like to avoid significant leaf drop this Winter if I can.

I have been looking into LED grow lights and I'm pretty intrigued, but I was wondering if there are commercial products out there worth recommending for home use? Anything that is really loud or unwieldy will probably be not practical. I was hoping to have something I could hang from a hook on the ceiling so that I could take it down during the warmer months.

Are there any specific recommendations or pointers that people can give me? I was looking at one of the UFO style ones on amazon, but the reviews are all over the place. I have gotten great advice on this forum in the past so I was hoping other people could help me out here.

I will be interested in the recommendations too. I just got my Lemons and mangoes inside and am using a Philips 120W plant light. Dont know if it will help but that was the only one i could get from a local Home depot.

Those are highly inefficient. They are primary for presentation purpose. Majority of the energy is for generating heat. A CFL bulb would be sufficient for a small lemon tree.

Sorry, I don't mean the LED light, I meant the Phillips plant light bulb. The LED is highly efficient. Just very pricy. I found LightHouse Blackstar is the most afforable one so far.

Ebay and Amazon has LED grow lights from a company called Gotham Hydroponics. I bought a 100w LED light from them almost 2 months ago. I've attached some pictures to show you what it has done. The big plant you see is a Lisbon Lemon Tree, so I felt I had to comment, ha.

The tree came distressed from Lowe's. I bought it in July and left it outside through September. As you can see before it went under the LED light, it had recovered quite nicely. The setup is what you see. I started the test on October 18th. The final pictures are in front of a window for better viewing but there was new growth! The growing room was in the basement. The temperature down there was not ideal, so I personally feel that the growth could have been much better if it was warmer in my basement. Not to mention the stale air and such.

The other plant is just a daisy I saved from the cold and as you saw, it drooped considerably. The next picture is three days of being under the LED light. I feel that LED's do work. My only concern at the moment which I'll post in another thread is when plants get too tall, at what height will I need to worry about supplement lighting if at all.

So with your LED fixture, when the LEDs burn out will you be able to replace them yourself with ease, and for how much?

eric_oh, I'm not smart enough to be able to replace them myself I don't think, however I do feel that the company I purchased from would be willing to walk me through it. I tried to put a grow light together myself with a kit and almost started a fire ha. But I feel that the lights are affordable considering the market. They also give you a discount for ordering over the phone.

If an LED light fixture is built properly, you will be replacing the whole light, with what should be several newer generations of LED's, by the time they burn out. If you have to replace any sooner - you got robbed or the light is intentionally wasting the LED's life for brightness, knowing full well that the light will fail long before it should. I'm sure an LED light vendor would call this a "trade off"

Lots of vendors claim their LED with certain watts, but that's not the actual power draw, quite often it's the maximum wattage of the LED multiply by the number. If the LED burns at the maxium wattage, the lifespan is much shorter or become inefficient quickly. Given my 240W LED light for example, the LED is 3W, but the actual power draw is 1.75W. In this rate, the efficiency of the LED is around 80% after 10 years of typical usage. Even after 10 years, the LED will probably still be bright, but just not that efficient.

They rate them by the bulb size, not actual power. This is my main concern with LEDs,Which I would like to use
One 48 watt unit actually draws 12 watts and a little "12 watt" unit draws 3 watts, useless except right over germinating seedling. . The best I can measure. So how do we figure the actual amount of light from them? Trial and error? To see if it is enough? I get mixed results with my light meter and don't trust it with LEDs. I have a 100 watt black star and it measures the same (light meter)as one of my 48 watt, one foot square one. An other 48 watt doesn't even come close.

Not all manufacturers rate them via installed LED wattage. There are higher quality manufacturers that rate them via draw voltage. This is one indicator of the quality of the unit. Not unlike stereo vendors, where the cheap ones rate in peak wattage whereas quality stereos usually rate in RMS.

I should note there is a HUGE difference in unit quality between vendors. Do your research. The high quality units truly do outperform HPS and are improving constantly.

I just installed the 240W LED from Gotham Hydroponics. It's insanely bright, I took my light meter and it's over 3000 FC reading in a foot distance. My aged UFO only reads a couple hundreds.
