Mars Hydro FC-E4800 PAR Test and Review

[@bobsmith3790]

FC E4800 and although it went together well it contained no manual or any other documentation. When I asked for help with that the just sent me a link to what was essentially a marketing add. I’m not doubtful about the light working, but for what I paid I sure would’ve liked the manual and stickers…lol…thank you doctor.

[@Smotpoker]

Lots of fun being apart of that live giveaway. Such great lights too. This diode placement and movable bars are 2 of the recent new light innovation that I enjoy. Both in one fixture. Great review, great work you put in doc💯💯🤘

@@Smotpoker oh I am very familiar. If OP had a $500 Apogee I'm sure he'd offer ppfd instead. But I figured I'd have a better chance of OP having a $30 lux meter, and I can get the rest into the ballpark from there.

Thanks Very much for another great video and giveaway Dr MJ Coco!

[@acktionjackson666]

Hey Mr. Coco I have kind of an important question regarding these lights versus the FC E6500. Apparently these smaller E-Series lights include IR and one other Spectrum that the FC-E6500 does not. I have two separate 10 x 10 grow spaces and I'm trying to decide between 8 of the FC E6500s or 12 of the FC E4800s. I'm also trying to fit nine rather large plants in each 10x10 grow space. Any suggestions? Thanks! PS. I'm curious to know if the loss of IR and the 380-410nm Spectrum is a major deal or not.

[@DrMJCoco]

I would not worry about the IR and the UV. I would probably go with the 6500s and if you want to add supplemental IR or UV you can do that with separate fixtures. I think the main thing you want from a grow light is PAR Flux! Grower Love

[@acktionjackson666]

@@DrMJCoco hey thanks a lot for the reply I appreciate it. I already have 10 of the fce 6500 here I'm going to use two of them for the veg room and I was going to use 8 for flower but with the lack of ir I was thinking maybe I could put two in the middle on each side and then surround them by 4 fce 4800s for a total of 12 lights 6 on each side. I haven't looked into any IR ruv supplementation not sure if that's expensive or if it's a large power draw in anyway or not.

[@RookieBuds]

Mars needs an "FC-R" version, this exact same light but where the light bars can also rotate a few degrees within the frame, would throw more PAR to the walls.

[@onestarflag9876]

Question: why does it seem like using light rails a thing of the past? All the YT videos using rails is 3-5 years old and use HPS. Seems to me a bar type LED on rails could maximize a larger space with better yields at lower cost per watt and could also be placed closer to the canopy.

[@Smotpoker]

Most people used them before to have less heat and maximize the space using hid. In today's led market there is such good distribution with minimal height and low wattage =low heat. It makes it pretty impractical....esp when you lose more height,+the extra costs and task that go along with them. This is a great question and hopefully the doc will come by and chime in too. I do however know a cocoforcannabis.com member named Choo who uses a chilled x600 on a mover , pushing 1200umols ..with fantastic results..note* his ceiling is like 15ft lol... grower love n great comment!

Dr. CoCo , it’s always a pleasure watching your videos. Happy Holidays to All My question is, Can you do a Par test on the Mars Hydro FC-E4800 in a 3x3 tent in measurements of 12” / 18” / 24” / 36” and 48” all at full power. I know it might be much to ask for but I would really appreciate it. If you can’t make a video about it just running the test and posting it on the mjcoco website would be awesome also Thank you Dr. CoCo

[@chrisbethmann3955]

Really tough getting past cost on this light, not a Mars fan, but half price of most

[@Headies420]

I ended up buying this light, great videos you have here. I am a very interested about spectrum. getting the right amount of uv, blue, green , red, far red and the ability to add extra far red and uv. aside from getting a more natural spectrum ratio I like to blast the plants with far red and or uv for around a hour a day to promote secondary metabolites. Also the amount of heat these put out is crazy, at least without comparing to other lights. can we get more infoon things that also effect our grows. Thanks again, grower love!

[@jayortiz8631]

I have a 4x4 tent do you think the FE6500 would do better than the FE4800 I'm not worried about price I just want max brightness and yield?

[@jaspercane6608]

I like the spread bar type of light much better than the large quantum-style board. Seems the lighting by being spread evenly across the bars is more efficient in penetrating through the canopy and with better heat dissipation.

Hi iv just got myself the fc-e4800. When I was putting it together I noticed the light bars are different. You have 3 A bars and 3 B bars. The difference in the bars is the ir diodes and the infrared diodes are in different places. I contacted mars hydro customer service about how to place these bars and in witch order. I received an email back saying the bars should be placed A,B,A,B,A,B. There is nothing in there user manual stating this. Or on any reviews that I have seen. Please contact marshydro yourself to confirm this information and maybe do an update on your review. Because surely with the difference in diode placement it would have an over all affect on light quality. Just thought I would say something as I feel this information to be important. There must be thousands of lights out there that aren't set up properly and not getting the quality of light the light is capable of.

It would be an advantage if you could adjust the angle of the outer LED bars a bit, so you could better illuminate the outer corners of the tent or area. Would be an idea, or maybe 2 additional bars that could be turned outwards at an angle so that they would shine into the corners of the tent or the area....

@@todgerx not a heater..your light is typically your heat source in your tent…good in winter..,bad in summer..when you buy a ventilation system for your grow tent, it pulls the old air out of the tent and pulls less air inside anyway the ventilation system either comes with a low, medium, high fan controller that you will leave on all the time or you can get the upgrade that has a temperature/ humidity controller that you set the ranges of the temperature and humidity that will turn on the ventilation fan on similar to an AC/ Heat system turns on when you environment inside is out of the ranges you had set it stand then turns off when the conditions are in the ranges you have set….which in the long run will save you money on your power bill by just turning on when your plants need it too…now it cost another $40 maybe less but it will pay for itself in the long run because the other system will run constantly….a good investment to keep your grow tent environment at optimal temperature and humidity at all times especially when you are gone out….check it out…Utube it…but for me it was worth the little extra and like I said it will pay for itself…

[@notyaavridge2660]

So my question is which is the better of the two, FC-E 4800 OR FC 4800

[@akig-alaskaindoorgarden4674]

480 watts is the minimum to call 4x4 "fully lit," so good for Mars bringing the E line in this class. But have you seen what Dr Coco did with 2x SP3KS in a 4x4? At $10/g, just the difference in yield pays off the SPs and then some every harvest.🤷‍♂️

[@Smotpoker]

I would definitely disagree with 480 watts being a "watt minimum " for two reasons, 1- watts isn't a measurement of the amount of light in the tent, the important thing is how efficiently a light can turn electricity into par photons.. I grow autos in a 4x4 using a 330watt fluence spydr 2x / and a chilled Growcraft Ultra x3 prototype type #1 (also 330 watts check out dr coco review). And we're getting 2lbs from 4 plants grow after grow. Please check out my KZbin or ig or my journals at cocoforcannabis.com I always enjoy talking lighting!

This one is underrated, I believe once you start the flowering stage, or even veg, the 730-740nm far red is what will make the difference with yield. If you watch the research done by Professor Bruce Bugbee on far red, all the plants ended up with higher yield. Factoring in CO2 and proper nutrition, the harvest potential should be on par with the FC-E6500 (I don’t think the E6500 has 730-740nm lights).

[@WestCoastCroppers]

Yeah the fce6500 is a veg light. No IR or UV Diodes

@@randomstranger2472 I would like to think that you would be wrong. But I am not positive. Though those Ir & uv LED’s are what help make the light full spectrum. Perhaps @migro has more info on it.
