KINGBO Dual Optical Lens-Series 600W Full Spectrum LED Grow Light for Indoor Plants Veg and Flower, Garden Greenhouse Hydroponic Grow Lights (B-600watt)

I ordered this particular light towards the beginning of December . It arrived before the stated delivery time in a discrete brown plain box . It was packed well and upon unboxing you can see the quality of this product . It is well made , nice feeling materials and aesthetically is very pleasing . I had looked at similar products from other companies but the quality and the price on this product can not be beaten . The quality of the lights is second to none for the price and is comparable with products almost double it’s price , I say that conservatively . It is a quality product . The built in fans run very quietly even after long periods of use and are no louder than a computer fan . The temperature increase while running is almost non existent due to the quality of the fans . It come with a set of hanging straps ( I think that’s what they are called) that are more than capable to support the weight of the light. I’ve currently been running the light to help with some Mediterranean plants and fruit and the results are wonderful . You are able to easily switch between veg (blue light with some red) or to bloom (mostly red with some blue) or run full spectrum (purple) with both switches on . Doing the latter activates the two built in fans which also aids in keeping the light nice and cool. The switches are of a good solid quality too, there really isn’t any downsides to this product. It does exactly what it describes and competes with premium models (double the price) with no issue . One thing I will say, even running the product for longer than 14 hours, it still performs perfectly , the fan is still very quiet and the temperature increase remains almost negligible. No issues as of yet and it has had way more than average usage. In my opinion it is Definitely worth the purchase and the customer service is second to none .

UPDATE2 - 1 year later...First grow not a great success due to my inexperience, second grow much better.4 lovely White Widow plants yielded around 250g - I did buy an additional 900w unit second hand, meaning plants had 1500w on them in total.Have just begun flowering 3 Holy Grail Kush in my 120x120x200 tent, decided on less plants as I'm using a scrog net. Many bud sites and I'm anticipating a similar yield this time around.Can't fault the lamps, working great and getting the results I want - highly recommend.UPDATELights performing great, bought an additional 300w unit after about 10 weeks, 5 plants doing very nicely into week 2 of flower, will be buying another 600w in a bit to hopefully boost the buds for the last few weeks.1st time grow, but happy I went for this lamp 😁After trawling through reviews decided on this unit to use in 120x120x200 tent.Arrived quickly, discreetly boxed.Seedlings responding well to light, runs very quietly and cool thanks to the fans. Tent is warm but not hot so recommend an eco-heater to get up to correct temp if necessary.Coverage is good at 60cm at this stage of the plants cycle, I'll probably buy another one in a few weeks when they're bigger to ensure best results in veg and bloom stages.Will update down the line a bit, currently very pleased with the buy 😁

So I purchased this arrived next day can't fault delivery.First impressions packagingPackaging was excellent I have every confidence that this light could arrive anywhere in world undamaged.First impressions light fittingExcellent build quality, feels very robust the hanging kit supplied is good quility more than capable of holding the light securely the only thing I'd say could be better is a slightly bigger snap hook as mine wouldn't fully go around my tent pole although was perfect on my rachet hanger, plug and cable is a good quility too which is nice, the fans are fairly loud but can barely hear them outside of the grow tent my extractor is much louder, and I'd rather have these fans doing there job properly then have cheap underpowered fans.When I first had the light I was finishing a grow, had this on veg and bloom (maximum power available) for 24hrs over 4 day period and could touch this light fitting without problem, it was only just warm which is excellent, I do believe using this light really help finish the grow off, I would absolutely recommend this light and will update my review once I've finished a complete grow.PrecautionsThe leds installed in this fitting are good quality and very intense even just this one light in my grow tent can strain my eyes so sunglasses may be advised especially of using veg and bloom at the same time, also make sure you read the instructions as putting this light too close can cause adverse effects especially on developing seedlings.Thank you for reading and I look forward to updating my review

Replaced a 600w HPS light for this, Have just done a First full grow of 'tomatoes'.Veg spectrum is spot on and could easily replace a 600w HPS light. Plants reacted well and grew Vigorously.Flowering diodes are good but they cannot be claimed to replace a 600w nor a 400w hps. In my tests your looking at a 250wHPS replacement. They do flowering dense crop of tomatoes but the light spread is a mere 1m spread of intense enough light for good yields.Overall I would reccomend this light for anyone growing in a 1.2m x 1.2m tent, very sturdy and fans pretty quiet. Nice look and no dead diodes. Great for any amateur growerThe low heat and low electric usage is a bonus

As an LED lamps maker in the past (I'm an electronic engineer), I could say this one (600w) is great. It has two powerful coolers that help the LEDs to stay cool, giving them more lifetime and making them more efficient. I used the lamp in a small closet. During summer, I would not recommend to use it at full power (in a small closed environment as mine) due the heat they produce. It's nothing compared to sodium lamps, but your plants would not be happy. I don't see how this product could be improved. It makes some noise due the coolers, but as your computer needs coolers for keeping the microprocessor alive, this needs cooler for LEDS. In short, I'd recommend it.

Lights arrived within 2 days , and were in descrete and sturdy packaging . Manual is very helpful with some good advice on how to use the light , to maximise its potential. My chillies responded well to veg settings on the lights , and I will update this review , in respect of bloom setting , when time comes for me to use that feature. Lights are very bright , fans not overly noisy , and the cord is quite adequate ( at least in my circumstances ) ..Customer service was very helpful with my enquirys , and quick to respond .

Was totally sold on LED after using one on adult plants. Got more flowering sites but cause no heat burn but light burn, even when very far away. Leaves look burnt and dry and are but not from heat which is misleading.Verdict is LED (including fables ones on aluminium plate which are useless) are not ready by a long way in this price range anyway. Grow shop guy had lots of same reports and why he won't stock them

The fans in LED are quiet and the dual function excellent for managing grow. I will be purchasing a second. Arrived quickly and packaged well. Had to contact customer services due to techinical problem at one stage and they were superb, responded promptly and actually cared about making sure I was happy with outcome. Thank you
