MARS HYDROSmart FC4800 Samsung LM301H EVO 480W LED Grow Light 4x4 1680Pcs Diodes Commercial Full Spectrum Foldable Dimmable Daisy Chain Grow Lamp for Indoor Growing

This light is unlike any other ive used so far in my 3 x 3. It's so powerful it was like turning on the sun. It's so sleek and couldn't be easier to assemble. If you're wanting an amazing light that will give you excellent yields from your medicinal plants then look no further. I can not shout about this light enough....and for the price you just can't go wrong. Whether you're a beginner or pro it is the dogs clems.It has the dimmer on the side and all the stuff you need to hang it. It's not heavy at all and one person can handle the job, easy. I have tried other competitors on the markets lights and they just don't compare and for me, I think they are more than enough for a 3 x 3 in a homegrown....sturdy, robust, gorgeous full spectrum, and very inexpensive for what you get...

The value for the money

As ive seen in other reviews the light was pulling a lower wattage then the 300w advertised but this is a very easy fix. Simply pop out the rubber plug on the driver and watch your watt meter while making very small adjustments with a small flat blade screw driver. In all fairness mine was at 285w which is within the +/- 5% allowed as stated on the light body but i of course adjusted it to the proper 300w.The light is very bright and fills out my 3x3 area perfectly, alot better than the 240x qb that this replaced. Im about 2 weeks into flower so we will see how it turns out but so far im happy with the light.I will update if that changes.Pros:Bright at 300wFills a 3x3 area perfectlyDimmable from 45w to 300wMinimal temp difference from 240w qbNice stickers in the boxCons:Adjustment needed to have the 300w quotedIf the grow space is bigger than 3x3 the light will most likely only flower a 2x2 space effectivelyFor the price range of the light the ratchet ropes are quite cheap but the wire hangers are nice and heavyClaims of 900g(3g/w x 300w) from the light may be a bit excessive imo but we can hope

parfait pour une box de 120 x120

Ne surtout pas se fier au titre et à la description qui mentionne partout que le produit fait 120 cm X 120 cm c'est du putaclic en réalité il fait 50cm x 50cm ce qui est loin de ce qui est écrit partout partout bref première fois que je suis déçu de MarsHydro la prochaine fois je me tournerais vers Lumatek qui ont l'air beaucoup plus sérieux et ne mentent pas sur leur produit

Just got it so I haven't used it for a full grow yet. just finishing a run in a 4x4 tent.But it looks and feels very well built and puts out a ton of light.It runs very cool as well, temps dropped 6 degrees Celsius after replacing my single CMH light with the FC3000 and a TS1000. That's roughly 450W led compared to 315 CMH and temps are down that much !I have some seedlings under it now and they seem to be responding very well to this light.I'll be doing this grow start to finish with this light and will update my review when it's finished.This light is best in a 3x3 and once I have the cash saved up I'll be buying a Mars 3x3 to go with this light and doing a full review on this light in a proper 3x3 tent.I've never had a Mars product let me down !

This light is advertised as a 300w lamp. As you can see on my calibrated power meter, I can pull out only 262 watts out of this lamp. Thing to notice: there is another dimmer on the back of the driver that can be adjusted with a philips screwdriver. Adjust it to 300 watts to ensure you have the advertised ppfd. The company should ensure the input power is spot on. Not everybody got a power meter.Another annoying thing: The number of advertised diodes: 1120. There is no such a lamp. The original fc3000 has 792 diodes, and the new model got 896. So don't get fooled by this.Appart these 2 small issues, I have to say I am amazed by the ppfd strength & distribution of this lamp and at the same time the lamp stays much cooler than the ts2000 series.
