I’ve watched them. Good work says i

[@joelhowe]

Boy, when I think of how much work it must be to take all those readings at all of those points for each of the distances and dimming levels...wow! I really appreciate all the time and energy you put into doing these tests and making these videos. You're the best in the business and your work really helps us make the best decision possible when buying lights. Thank you!

[@Albopepper]

Thanks Joel! I'm glad to be able to help people by providing some reliable data. Your kind words are greatly appreciated!

[@7munkee]

I value his thoroughness and honesty in testing these lights so much that I bought one today from his link. I've been researching wich new light to buy fore a week now.

[@Gojjah]

He actually stood on the light, im dead 😂 love this duder

[@Albopepper]

Hehehe. I told Maxsisun the only way I would test the light was if that included a "step test". They agreed! :D

[@shakaama]

omg you're still on youtube. that's awesome. I used to watch you as a kid. I no longer grow plants. I gave up when I moved.

[@kele1264]

Hey there Aldo! It always makes me smile when I see there's a new video from you! I love your detailed reviews and all the information you present. Thank you!

Thanks so much for that! I really appreciate your support on my channel. :-D

[@williamfoster4268]

Dude, your light reviews are awesome and go into much detail. I appreciate it!

I used my Chase rewards and got this light for $76.46 shipped. Thanks for the honestly and thoroughness. I also bought 2 Atreum Hydra 1000's because of your review last year.

[@allenwilliams6561]

I bought this light at Xmas…paid $250..I put it in a 3x3 tent and have been happy with my grow so far..Did a lot of research and this light is a good bang for your grow budget….I already have a FCE 4800 Mars Hydro in a 4x4 and it’s doing excellent with my 4 Blue Dream Autos (Day62)..Big frosty, sticky buds..I have had ,any board lights but since switching to bar lights I have seen better results on my outer edges perimeter because of the more even light and par distribution…

[@allenwilliams6561]

Bought this light at Xmas…on sale for $250… got a 3x3 tent…this is a good combo …

Just saw a video of you 5 from years ago. You seem to have lost a lot of weight. You look much healthier now👍🏻

[@Albopepper]

Hi Timothy! Yes, I've been eating a plant based diet for 4 years now and the weight, blood pressure and cholesterol have all come down. Thanks for sharing your observations! :)

[@cameronjohnson6765]

Really appreciate all your videos regarding lighting, while I have watched all your videos and reviews in recent months on different lighting, I'm curious what your suggestions would be on just simply starting seeds? For a home garden? I may have also missed something in your recommendation speaking about that. Thanks so much!

[@Albopepper]

Thanks for watching Cameron! For seed starting, I would match the light to the growing space. Is it a window sill, a wire shelf, or a table top? Different form factors of lights are suited for different spaces. Either way, I would certainly go with some decent quality LEDs, not fluorescent or HIDs. And select a light intensity appropriate for seedlings. That means PPFD levels from 200 to 500 umols, depending on plant type and light cycle.

[@cameronjohnson6765]

@@Albopepper That makes sense! I guess it will be on a wire shelving unit or a table top. It can be very overwhelming trying to pick a light given variety of lights out there.

[@CurieBohr]

Fantastic review. They should not only let you keep this light, but send you another.

[@Albopepper]

Hehehe Thanks for your kind words! I appreciate your support. :-)

[@casley1992]

Not only are you so intricate in detailing every aspect of what there is to know about light, you are so easy to understand and make this a really enjoyable way to learn, so cheers for all your hard work and vids! BTW I have bought myself a Greenfingers GL-320 bar light which is nearly identical to the one here, was wondering if you did any testing on Greenfinger products? I'm not sure if they're international as I got mine here in Melbourne, Australia.

[@ipadmini8173]

[@Road_Rash]

I just bought a SZHLUX PT4000 bar light...still waiting on it, should be in today...I bought it before doing a ton of research & the more research I do, the more worried I am about what's going to show up here...I have no way to test this light to find out what it'll do & if it was worth buying it...could you do a review on the SZHLUX lights? When I ordered it, I was mainly looking at the effective footprint of the light & it's supposed to cover a 6'x6' area.

[@drewmarquezsgoal4025]

Can you test the vanect led light sold on Amazon? I can’t find any information about it outside of Amazon.

[@lanceowens5902]

Would love to see you do a video on the Mars FCE series still great video and food for thought

[@robp4564]

Thank you Albo, have been looking at this light. Mind made up by your review, replacing 300w CFL bulb with one of these looking forward to seeing a difference!!!

[@tonykristhiofan1113]

Great video! Not sure i need something that big, but still very informative Oh yeah i need some help, i have a small orchard of papaya trees. They used to be pretty fruitful, but this last few months they haven't been fruiting that much. All the flowers and small papaya drop off the tree before they are ripe and the one that do get ripe is smaller than what i used to harvest. Some of the trees also just straight up die without any prior signs, both the old and young ones. Any tips?

[@Albopepper]

Thanks for watching! I've never grown papaya trees. But if I come across anything I'll let you know!

[@uriel-heavensguardian8949]

Ok your other video you did on grow lights. I am looking at the spider farmer sf1000 for my 4x2 tent. I was also looking into the bars lights. So am I assuming you suggest this company for bars lights? Thank you for your videos. I constantly rewatch them. I’m only growing one plant. I’m using a grow light someone gave me and it has no information and no brand name printed on it anywhere. Better to be safe than sorry I think I aliens replace it. But I’m in flower now so it maybe alas too late

[@OffGridandOutdoors]

Hey if you ever had time and resources it would be cool to see your thoughts on the Barrina full spectrum grow lite bar from Amazon (comes in a 2ft and 4ft version). If their published spectrum is realistic, these would be a good light supplement. But unfortunately on Amazon, they do not publish much info (umol, etc)

[@OffGridandOutdoors]

Oh ... I'm referring to the LED not the T5 versions :D

[@8ending8ranches]

i love my MG3000 but man it is hard to manage the heat during day hours in flowering.

[@melangkoh4184]

Mr. Pepper i have another question please, how does it come that the samsung Diodes Lm 281+ and the 301s are so close to each other in efficiency? On paper the 301B and H put out a good amount of extra light with the same power (I think something like 30%), but in reality and in Tests, a decent lamp with Lm281s is maybe 10-12% less efficient only. And the price for the 301s is 10-14 times as much as the older 281. A 281+ diode is actually only 1 cent when you buy a pack of 4000 pcs. By the way, id like you to test some really cheap lamps. There are interesting panels on Ali express, like a 100W panel with 336 LM281+ diodes for only 40eu. No heatsink and no dimming, but a lot of diodes and id like to know if such a lamp can hold up with the Viperspectra P1000 for example. I wouldnt be surprised at all if it does.

[@ast-og-losta]

Did Maxsisun go out of business? Cant find their lights anywhere.

As always, flush with useful details! Was that some sort of strange pun changing a light while standing on a light? Hmmm....

Hi everyone! Hoping you can help since youve reviewed it in real life: i have a 3x3 tent -im trying to decide between MARS HYDRO FC-E3000 and Maxsisun mg3000 Thoughts?! Thank you!

[@Albopepper]

I haven't examined the FC-E3000, so I can't say definitively. However, looking at price and raw specs, the Mars Hydro model does seem to be a good value.

[@tonyb.5768]

who is better xs4000 or sp3000 thank you

[@Albopepper]

They are not comparable. One is 480W, but the other is only 300W. SP3000 has a narrower coverage area. So it depends on your application.

@@Albopepper Oh no :( Do you have recommendations for hooded grow lights? would be cool if you could do a video about them, seems like the options are scarse and for someone like me growing open at home those hoods are important...

[@melangkoh4184]

Hello Mister. If LED are more efficient when underpowered, wouldnt it be much more efficient to run 2 100Watt-Growlights at only 50% Power instead of a single 100Watt Light at full power? As i understand, LEDs lose efficiency pretty dramatically the more power goes through them. I think with this method even cheaper diode boards like the older LM281 would be more efficient than even the best diodes. Because the difference is actually not that big of a deal between different diodes,

[@Albopepper]

In concept that seems to make sense. But in practice, the lights don't have a huge boost in efficacy when dimmed. You could compare these 2 reports for the same light with Samsung diodes & Mean Well driver: albopepper.com/ATREUM_HYDRA-1000_Report_20210402.pdf albopepper.com/ATREUM_HYDRA-1000_Report_DIMMED.pdf Even when dimmed to 1/5 the power, the light still had the same PPE.

[@melangkoh4184]

@@Albopepper thats weird. I have seen a couple of people describing now that LEDs lose efficiency, the more you power them up. guess i have to wait until i have my own lghtmeter/PAR meter.

HLG still won’t let u test the Diablo? They should. The maxisun is a nice light for the 3x3 .

Thanks for watching Ben! I don't test HLG products. Not because they won't let me. Because I told them I wasn't interested. In one of my videos from 2 years ago, I mentioned the term "Quantum Boards" in my opening comments. It was just a general reference. They threatened to sue me because they had just recently acquired exclusive rights to use that term as a Registered Trademark: albopepper.com/QuantumBoard.pdf I reposted my video & told them I didn't want anything to do with them.
