Phlizon 2022 Advanced PL-4500 Full Spectrum LED Grow Light with UV & IR - Samsung LM281B Dimmable Daisy Chain Indoor Plant Light for Hydroponics, Greenhouse & Home Gardening

If you never heard of this brand don't let that scare you away switched from a well known brand and this beats it the price you can't beat and the PPF report is really close to what they say love itIt’s not bad for the price.. what do you really expect for $70 it’s just enough to keep seedlings and small plants in veg no way this could be used to flower anything and get any real results but will use for a clone light once they get roots. Not a bad light it’s just only strong enough for a veg lamp in a 3x3 but it does the job just don’t expect to be able to run it from veg and also flower you won’t have enough power for thatI have used so many lights over the years that they've all started to blur together. I've purchased flagship ballasts, magnetic, digital and custom hand built hand wrapped. I've used every different bulb that might give me an improvement in performance. I started test driving LED lights, ufos, panels etc. back around spring 2004. I determined that the technology just wasn't ready yet to make them worth swapping out with my magnetic set ups. When COB chips came to prominence I again gave them a shot. Still not practical. Then chips really started to improve in the last few years, blurple fell off to the wayside and I realized that the LED Revolution was finally going to kick off. Well folks that's where we're at. The tipping point is here. Several manufacturers have fielded serious lights finally able to replace the venerable 1000 watt HPS. Big coverage, good penetration with enough head room to run different strains and sizes of plants. I have over the last several months purchased several of this generation of lights from four of the big names in the game and they are all worth using. From Philzon, using Samsung chips, I've gotten a PL-1000 and the PL-4000. For the price the performance of both makes them the honestly best value of this generation of LEDs. I really don't know what more I can say. I guess the fact that the 4K really covers 5×5 feet with a measurable improvement in plants performance over a very well put together HPS 1K set up. The PL-1K easily out runs a 400 watt MH in one of my veg/mother plant/papa plant spaces and plan on replacing all of them. With various lighting schemes I'm dropping 60-75% off of my power usage with a performance boost. It just doesn't really get much better than that.This board comes in $100 cheaper than the equivalent spiderfarmer and it’s gonna blow everything I’ve used in its pricepoint out of the water. These are authentic lm301b’s and the spectrum is dialed in perfectly. I have grown with led’s since they became a thing and I cycle through a lot of different amazon and alibaba lights. From experience, I can tell right away when the spectrum is off on a new light. Anything with the cheaper smd diodes I find inadequate and I have a couple alibaba lights with authentic 301b’s that cause weird bud growth cuz the spectrum is off. The viparspectras and mars hydros are fine for veg but they do not compete with proper quantum boards like this. Nothing I found on amazon at this wattage With authentic Samsung chips came in this cheap.The board runs very cool. It’s cooler than everything I own if I’m being honest. The lack of heat sinks isn’t a factor since the board is very thin. Don’t let that be a turn off cuz this board has excellent manufacturing. The dimmer doesn’t turn the light off but you’ll be connecting this to a timer anyways so who cares. Where you’re saving money is on the driver but I’d rather cut corners there than on the diodes. I argue boards this size don’t need the more expensive meanwell drivers. Sure, you could probably eek out a little more power or efficiency but that’s negligible for this size application. I hope this is going to be the game breaker I expect it to be. Everyone else is gonna have to lower their prices or use better chips to compete if this board becomes popular. The new vivosun with 301bs looks good too but it only comes in a little 100w. I expect the new vivosun and these phlizon boards to be the ones that shake things up for the next year.Started out with one of these (the 2000W version), it made a huge difference , noticeable from the red and blue phlizon I was previously using (600W red and blue).In total I ended up buying THREE 2000W versions... using one in my flowering tent, one in my veg tent, and my wife is using one for regular plants.If you're growing in a tent, you should never need to go above 7 or 8 setting. Full blast on this light needs to be on the ceiling of a room. It's really bright. Maybe not as bright as one of the more expensive MarsHydro professional grow lights, but this is way brighter than a blurple, or High Pressure Sodium / metal hallide setup. For the price its great.Then I bought an additional 1000W (smaller) version to do seedlings and clones.. again I only run it on 6 out of 10 for the light setting. It too is extremely bright.The light did NOT burn my plants so far. So far so good for the whole process from seedling to flowering . Keeping them about 18 to 24 inches under at all times. Keep your plants a little bit further from these lights than you normally would with regular lights I would suppose, or turn down the lights a bit , the upper setting 8-10 on this "new 2020" phlizon is pretty much overkill for a small tent.The lights work as I expected (or better than) that's for sure.Trying one of these to Replace a King LED 600w light that died. So far, so good. Immediately noticed that this light runs cooler and I like the dimmer control.BE AWARE THIS ADVERT IS MISLEADINGThe product itself is satisfactory but the advert falsely advertises a greater wattage equivalent to what it actually is. Please read the advert fully before purchasing as correct output sizing and wattage/volts is not ambiguous!Want a light but can't afford/justify those £400+ ones? This is your alternative. It works fine. You might not be getting the same yield as the super high end lights but you are paying a quarter of the cost. It is 100x better than those cheap blurple lights.At 100% power it draws 190w from the wall. So if you were to run this light for 18 hours a day you will pay around £5 a week in electricity.Something to be aware of is the shape. It would work best if you wanted to grow in a rectangular space. Probably perfect in a 3x2. However in a square grow area it feels like there isn't a great way to set it up to get an even coverage.It's also quite weighty. This isn't a problem but you need to be aware of it when lowering it on ratchet ropes.Finally, the kettle lead it comes with is a little short. Some other companies supply their lights with 2m kettle plugs which is lovely if your grow area isn't right next to plug sockets.i have one plant in a 4x3x60. ihave a mars ts1000 for it, i thought ild go with this phlizon light because of dimmer , that works fine. but light output compared to my ts is undeniable. ts wins. i bought it at 189.99. its now 234 . thats for sure not worth itWhen you realise it's not as advertised it will take you 14 days to receive a refund!NOT 2000 WATTSSo far I'm very pleased with this purchase. It seems to be of very good quality and straightforward to set up. The supplied temperature/ humidity monitor was doa but was replaced very quickly by customer support. I did a fair bit of research before buying this and am very happy with my purchase.
