## Description

desertcart.com : KINGLED KP4000 LED Grow Lights with Yield LEDs 5x5ft Coverage Full Spectrum Grow Lights for Indoor Hydroponic Plants Greenhouse Growing Lamps Veg Bloom Daul Mode : Patio, Lawn & Garden

Review: Very nice light at a quite good price - Great quality, fan cools the light extremely efficiently and both the spectrum and intensity match with advertised specs (which is not exactly a common thing in desertcart unfortunately). Botanist with 20 years in professional and hobby horticulture, if we’d have had these LEDs 20 years ago they could have saved us a lot of energy and headaches. Fantastic tech, decent price, easy to use! Just make sure you have a surge protector stationed outside your tent/grow area as the cord is not the longest. I run all power/connecting cables for my lights to through the ceiling rafters in my basement so it works perfectly. The light itself attaches to the ceiling via the usual grow light attachment cables with the height being easily adjustable to raise or lower the light as needed.
Review: Professional results at a reasonable price. - My 2nd year using the KP4000. I start and grow several varieties of seedlings. Mostly Geraniums. I have several Grow Lights from other manufacturers and like my KP4000 the best. Only suggestion I would make is to include a chart as to how high to hang the light above various seed-starts and seedlings (6in-12in-18in, etc.) so they get the preferred amount of light for each growth stage. I would recommend these lights to anyone wanting a quality effective product at a reasonable price.

### ⭐⭐⭐⭐⭐ after complete refund and replacement...the review
*by S***Y on August 30, 2018*

After getting a replacement for my defective unit, I can give a fair review of this light Top brand LED grow lights are insanely expensive. How is it possible, then, that a light like the 1000 watt King Plus sells for so much less? It must not be any good, right? Not quite. While it is true that this light can’t match the top brands, it still does surprisingly well and, considering the price, it may actually be a better value. This is great news. It means it is now possible to grow with LED light without spending a fortune. In fact, a light like this actually costs less than the equivalent HID system. In addition to a lower purchase price, it also costs less to operate, using far less power and generating far less heat. King Plus 1000 Watt Grow Light Features Uses 185 watts — save about 50% on your electric bill over HID lights Equivalent to a 400 watt HID system — but costs less to buy AND to operate Full spectrum light — can be used during all stages of growth 2.5 by 2.5 foot core coverage — nearly equivalent to 400w HID Epistar 10w double LED chips — deeper canopy penetration than 3w or 5w chips Runs on AC85-265V — will work in any country Rated for 50,000 hours — 4-5 years with no bulb changes 3-year warranty — risk-free purchase Includes light, hanging kit and power cord — everything you need to start growing immediately. Advantages king plus 1000w par and coverageThe King Plus series of grow lights was redesigned to use two larger 5 watt Epistar chips together in a single diode. This results in what is basically a 10 watt diode. As such, the light from this fixture will penetrate more deeply into the canopy than the light from a fixture using a single 5 watt chip and much more deeply than any 3 watt chip light. The PAR value in the center at 24 inches from the canopy is 447 umol. At one foot from center, the PAR value is 313 umol. At the corners 3 feet out, it is 91 umol. The core coverage area at 24 inches is 3 by 3 feet. If you move the light back to 30 inches from the canopy, you get a PAR value of 230 umol. Moving it closer gets you 595 umol at 18 inches, 958 umol at 12 inches and 1901 umol at 6 inches. The main reason most LED makers don’t use 5 watt or double 5 watt chips is heat output. More powerful diodes naturally emit far more heat than smaller ones. In order to use them effectively, the light fixture must have an efficient cooling system that can handle the increased heat output. king plus led spectrumKing Plus uses a thickened LED board (3 mm compared to 1.6 mm for other brands) with holes in it to help heat dissipation. In addition to the vents in the board the fixture has two fans and glass form convection, all of which combines to effectively handle the heat generated by the powerful chips. In total, there are 100 of the 10w double-chips on this fixture. They are a mix of red, blue, UV and IR. The exact breakdown of the color spectrum is as follow: 71 red diodes (620-630 nm and 655-660 nm), 14 blue diodes (440-450 nm and 450-460 nm), 8 yellow diodes (605-620 nm), 5 warm white diodes (3500-4000k), 1 UV diode (380-410 nm) and 1 IR diode (730 nm). This gives you a great mix of light that is the exact spectrum plants need. It is a spectrum that will work for every stage of plant growth and the addition of IR and UV serves to boost the quality of your harvest. Natural sunlight also contains these wavelengths, but the majority of LED lights don’t All King Plus fixtures ship with a power cord (available for US, UK, EU, AU, JP) and hangers. They also come with a 3-year manufacturers warranty, so you can get your light repaired or replaced if anything goes wrong. Disadvantages The big, glaring disadvantage of this light is the false advertising. The manufacturer calls this a 1000 watt light, which implies that it is equivalent to a 1000 watt HID system, like some of the top-brand 1000 watt lights. While only the best 1000 watt LED lights are actually equivalent, this one doesn’t even come close. It is basically equivalent to a 400 watt HID light. I hate when manufacturers use misleading names for their lights, but I suppose I can understand the reasoning. So many of the lower-cost (and even many of the big brands, like Kind LED), misrepresent what their lights are actually capable of and if you don’t, people will mistakenly believe your light is not as good. If you can look past that, you’re still getting a great light, as long as you are aware of its actual capabilities. It simply is not going to replace a 1000 watt HID light or come close to the top 1000 watt LEDs on the market. It is a 400 watt equivalent light. But as a 400 watt light, it’s a good one that sells for a very good price. Summary of King Plus 1000 Watt LED Grow Light Review king plus cooling systemShould you get this light? That depends. It is not going to come close to matching a real 1000 watt LED plant light. But it costs so little that you could get many of these for the price of one top-brand light. Let’s look at an example. Say you want to light a 10 by 10 foot area. Some of the best lights on the market are the Black Dog Phytomax-2 line of lights. Their 600 watt fixture (equivalent to 1000 watts HID, because they label their lights accurately) costs $1899 and covers a 5 by 5 foot area, so you’d need 4 of them to cover 10 by 10. Total cost to light the space with Black Dog lights: 4 x 1899 = $7596 If you went with this King Plus 1000 watt horticultural light, you’d need a minimum of 9 lights to cover that area, but let’s just say 12 to be extra sure we have enough light. Each light usually sells for around $200 (though it can cost more, at times). Total cost to light the space with King lights: 12 x 200 = $2400 As you can see, although you need far more lights, you still come out way ahead in terms of expense. That said, a Black Dog light is obviously constructed better, so the chances of getting a defective light are lower. Those chances aren’t high with King Plus either, but definitely higher than Black Dog. Yes, King give you a 3 year warranty and you can return any defective fixture, but you still lose time. Whether the cost savings are worth the potential loss of time, no matter how small the chance of it actually happening, is something you will have to decide for yourself. Personally, I tend to always go with the lower cost option, especially if there is a warranty. After reviewing the Kings Plus 1000 watt LED, I can definitely recommend it and all other lights in the series. But not as a 1000 watt light. As long as we agree
