Umm, yeah,whole idea of this post to see if got ripped off or if any one has history with this type of light. Hydro guy says you can use it right though to flower,have no knowledge bout LED’s so thought it be good idea talk to you guys

@spongefiller LED Lights aren’t my deal but I just bought a 400 watt COB LED with 200 actual watts and paid $100 on amazon
The light I linked is made by Mars Hydro and is a very reputable company.
But let me tag a couple of guys to guide you better than I can @Niala @Countryboyjvd1971 @BIGE
https://www.amazon.com/Spider-COB-LED-Grow-Light/dp/B017FQJXLS?tag=greenrel-20
There are touting the one you bought as the latest innovation and most powerful 400 Watt COB LED on the market. I believe it is how they worded it.

Hey bob31,yeah they make it sound better than snoopdog’s bong.Been doing a bit of snooping myself and this growfresh mob have pattened whole series of these spider cobs. From 90w up to 1600w. They have epistar chips,have no idea if their any good. 3year warrenty though.

That light looks nice but from the link I didn’t see the actual watts drawn they say 108 watt per some but is that rated or actual watts ?
Most cob lights will run half of rated power meaning if you have 4 light and they rate the lights get at 400 watts ea light would be running at 50w true but can run up to 100 watt just not as efficiently so I would see if you can find that out
If it was rated at 800 I would think actual watts drawn somewhere around 400 ?
I’m at work right now and can’t do the research myself
Spectrum looks good tho 
Epi star are good just a older technology new cobs are made with cree style cobs but epie star are fine

Hi mate,apparently they draw bout half,just like you said. 4 lights each 90w. Hydro guy sold me by saying they will work right through to flower. No changing,just keep raising,does this sound right to you. Mate big relief to hear you say chips are ok

When they say 400 watts that is what they are equivalent to. If you look at a package of household cfl of led bulbs it will saw something like 12 watts equivalent to a 60 watt bulb. Its the same principle with these lights.
Ok, I just found it in the product description. They are claiming
##“Actual Power consumption 265 watts”

OK,will it be ok right through all stages,do you think? I realize only 265w, but is that full spectrum at 370-850nm, Also par at 1829.2 umo l and 7280 lumens. Haven’t got a science degree or professorship so FIIK.

The light should work fine but since I don’t own one I won’t make any claims to how it works spectrum is good for full grow cycle and yes full spectrum
The price is a little high tho imo
I have the same one bob has and you could get 2 almost 3 of those for one of the ones your looking at and they draw 200 but with 2or 3 you’d have better coverage and more watts good for thought @spongefiller
Thanks @bob31
Ps I just looked at price again and you could get 4-5 of the cob light bob and I have for same price bro

It just pisses me off so much when your told by reputable business owner that the light you’ve saved for like the last 6mths is 'THE BOMB" quoting it does this and does that,only to find out he’s full of shit. I understand concept of buyer beware and really should have researched better,but f!#$ me,$500,you would expect to get something better than a square box with 4 glowsticks in it. No offence to you guys,your honesty and candour are very much app. I’ll stick with it and hopefully send some pics when and if harvest time. There’s a lesson in all this somewhere,dont be conned by smooth talking hydro guy while dreaming of massive,resin dripping,roof touching,window smashing trees of epicness. Thanks guys

It’s not a bad light you have @spongefiller, however, you pay way too much… Change your hydro supplier… Do not be hard on you, the shame as to be on your hydro guy or his employee…
You can have the same light at half this price on amazon…
For the light specs, it have a full spectrum, that is good, the 7280 lumens is weak for a COB light , you can expect at least the double of that for the price you pay… The 120° beam angle is most probably the reason why, should be 60° or 90° for a better concentration of light. At that kind of price, you can expect CREE or Citizen Chips On Board (COB) not Epistar… Talking about Epistar, i’m very surprise that the COB is that weak, maybe the driver on that light is the reason, further investigation is needed. For the umols, I have to make futher research as well but it’s seems either high as low depend if it’s the DLI or the PPFD numbers… The life expectansy is low for that price, should be the double (100 000 hours) again, I suspect the driver maybe the cause…
Anyway, like I said, it’s not a bad light, but I am much more critique when that kind of price is involved… And you should be good for a nice growth with it… Since you seem to have already bought it…
Hoping that’s enlighten you a little, and if you need some suggestions, just tag me or bob or CB, we gone a help you with great pleasure,
