LED Grow Light 600W with Adjustable Rope Hanger Full Spectrum Indoor Grow Lights for Plants Veg&Flower in Greenhouse Tent Plant(Replaced 600W HPS Light,Actual Power Consumption 90-110W)

I do not usually post reviews, as a feel a product is what it is, but in this case I felt obligated to write one since I am fortunate enough to own a PAR meter. After testing the lights in a totally dark room, I found the PAR values to be less than half of what the product pictures say. At 3 feet directly below the light source, the PAR value was only appox. 150umols/m^2/sec.

A total POS. Sent it back to Amazon yesterday for a refund. I've had quite a few LED grow lights over the past few years and this one doesn't put out much light. NO way this one is even close to 600w. Put my meter under it along side of a 300 watt LED grow light I have .and the 300 watt is brighter. I guess the market is getting flooded with cheap imitations of good quality lights. This is one. Period

Just what I expected. Great product!

worked just fine for me, would recommend

This is my first grow light and it looks really clean. It was very easy to set up and install. The two internal fans are quiet and seem to fit their purpose... Time will tell. Overall, my first impression with the 600W grow light is that, it's worth the $85 (or so) bucks that I spent and it's going to be a great asset to me and my plants. I would recommend this product to those looking for a 5-7 plant grow light. Thanks and hoped this helped.

We have already gotten half our money back on the purchase of three of these lights in one months electric bill. Went from $324 to $156. The plants love em and growing better than with the sodium or halite lights (much cheaper too). Love the 120 day guarantee (one growth cycle) for returning. So far, we have no complaints and have plans to purchase three more if still available when the time comes.

I've only owned this light for about 3 weeks but see a definite improvement in my tanks corals and really rate the build quality and ease of programming as top notch. Mine is the 24" and came well packed . It had decent instructions for the operation of the unit , and came with the hanging kit and a remote control for the light. The remote and the front touch panel can select all modes for the light. There are presets ( MOONLIGHT, CUSTOM, SUNNY, CLOUDY, and one other I can't remember ) for light intensity if you want to use a setting used on-the-fly or are too lazy to program the unit . : > ) Smile!First thing to do ( as I do with anything metallic that will be hung over salt water) is to wipe all metal parts\surfaces with a rag that is thoroughly impregnated with non-toxic mineral oil ( aka baby oil but without the scent ) to prevent rust. Next thing was to understand the the height adjustment fittings can be adjusted to both extend and retract the steel wire used. Initially I let out ( extended ) the steel wire and then when trying to retract ( shorten the wire ) I could not figure it out. I finally realized that ( DUHHHH! ) you must press IN the nipple end of the fitting as the other end that extends or lets out the wire only works one way ( extending it )Sounds simple, but confused the hell out of me at first.The fit and finish of the light is great , and makes one wonder why anyone would pay hundreds more for an "american made" one that are commonly touted as being superior and use the SAME CHINESE MADE COMPONENTS. This light seems to be made at one factory in China and simply distributed by many companies under different names. It's the same light.Programming could not be easier , and you can do the light intensity in 1/2 and 1 hour blocks of time for a 24 hour cycle. I start mine at 6AM with just the blue lights at 3% then at 7AM 8% with 2% full spectrum kicking in. I then increase intensity accordingly until at 12 noon the both the Blues and Full spectrum are at 100%. At 400PM I progressivily lower the intensity with the Full spectrums being the first lowered and then the blues. I do this until at 10PM the ratio is 25% Blue to 15% full spectrum and keep lowering intensity until at midnight only the blues are on at 3%. giving a moonlight effect.This moonlight effect is fascinating, and beautiful to see, as there is a distinct shimmering of the light on the sand and corals and yet the light is tremendously subdued. Certain corals start to polyp out after about 20 minutes under this light and this is amazing to see and show guests. Invertebrates that were hiding in the brighter light now start to come out into the open. Just really cool to view the tank's corals in this subdued "moonlight ".My lights are programmed to go out completely at about 1AM.The fixture is about 23 iches wide and about 2.5 inches high with a front to back length of about 8 inches ( don't hold me to be 100% on all of these measurements except the width ) . The fixture does have a female plug for 220 volts but only a 110 volt power cord is provided. The light can be hung and it's position adjusted easily with the supplied hanging kit.NOTE: Always make sure BEFORE making height or angle adjustments the the lamp has a "failsafe" attachment that will prevent the lamp from falling into the tank should you slip up while adjusting things. This can be as simple as a piece of rope attached to the light that will act a a temp support and whose length prevents the light from falling into the tank. After your light is adjusted and secure, you can take off this failsafe rope. I have mine secured with both a chain and a rope/pulley system ( to adjust height ) with the secondary chain being the failsafe and it's length will prevent the light falling into the water if the rope/pulley system fails.YOU MAY THINK THAT THE LIGHT CANNOT FALL INTO THE WATER BUT IT CAN!!Now with that warning out of the way.......,more details...., my light is 2.5 inches above my 90 gallon tank which is 24 inches deep, 48 inches wide and 18 inches front to back.The light penetrates well to the bottom of my tank, however the effective lighting width of this 24" light is about 33 inches so although you CAN use this lamp on a 48 wide smaller tank there will be two "dead" areas on each side of the last 5 or so inches of the tank. So two of these 24 " or two 16" may work better. My solution ( Until I get with another 24" or a 16" is to move my corals within the 33" light spread of this light. The intensity of the light has no problem providing light for the inhabitants on the tank floor as mentioned before.I mention this , in case anyone is considering just buying one light or two 16's.... the one 24" CAN work but you'll need to move any light needing corals within the 33" light spread of the 24" ..., so there is some compromise to be made if you go that route on a wider tank. For tanks like a 40" breeder ( popular size ) or a 36 " tank a single 24" light will work just fine.How is the color rendition?Very natural , without the harshness ( when the light is at 100 % ) that some other Blue\Full spectrum combo lights have. With the full specturms at 100 % there is no overly bright white\yellow peakiness. Of course , this is just my observation with my eyes and without the use of a spectrometer, but I mention it anyway.Fan noise is almost silent.., very quiet.Light duffusion seems to be focussed towards the tank's width (a 90 degree spread? ) and unlike older lights , the lamp does not spread the light all over the place, just where it is needed ( in the tank ).All in all, I would recommend this light and would highly recommend this light over the tremendously overpriced programmable lights offered by other manufacturers. If you feel that spending lots of money makes a product better , well that's up to youFor me however, it was a no-brainer.It's now April 2016 and I want to recommend Hoobie Bug once again for this time Excellent Customer Service way after the sale. Through my own fault I brole the display in the 24 inch lamp by a slight accidental immersion in tank water very little water entered the lamp and I was able to wash out the salt water with fresh RO water completely. No water entered the LED board. The LCD worked ( I could select modes with the remote ) but I could not view the menu as the LCD apparently died. Contacted Hobbie Bug who responded quickly send me advice on trying to get the LCD screen to work somehow but unfortunately no joy. I then asked for a replacement LCD unit ( which was reasonably priced by them ) and they quickly sen tit out in no more than three days. Very fast and constant communications all the way. I highly recommend this lamp and this company.

It's perfect. When you buy something online it's hard to tell if you're gonna get a cheaply made low quality item, but that isn't the case with this item! It's good quality and works perfectly, I couldn't be more pleased.
