Sorry i missed the live. I really like that wattage meter and how growers can now equate a percentage to ppfd at a certain height. Great info to be able to reference! I agree its great to see the thoughts goin into these lights a little efficiency here and a little there- adds up!
Watched your Video last spring and was sold on this light. Bought it and LOVE it... Thinking about getting another one, or just grab the Atreum 3200 and call it good. Thank you for your knowledge sharing sir! ALWAYS Excellent!! This light works well with the Ac Infinity Pro Controller. The only downside (if ya wanna call it that) is the loss of fine tuning the driver; the controller uses it in increments of 10's, so.... it's not much of a downside honestly, it allows you to set it via the phone app. or the controller itself, and lets you do life while growing. Thanks again for all your knowledge sharing sir!
I have 2 of these I bought for a 2x4 tent. They reinforce each other on two sides and give a fairly even 800ppfd across the entire 4 feet. I love them and would like to get 2 more when money allows for clones etc. I also have a 300-watt Maxsisun 4 bar light for my 3x3 flowering tent.
I'm trying to find a good grow light setup for my small nursery. It's unlikely I'd be able to have mylar walls around the plants, they'll just be on shelves in the greenhouse. Will this grow light output enough to carry seedlings to an advanced stage? Best I can figure is that one of these lights will only cover two standard nursery trays worth of seedlings, but I don't know whether it'll be bright enough to take them to an advanced stage (e.g. tomato seedlings up to 30cm tall). All the detailed reviews of various grow lights I see are talking about cannabis in grow tents, so I'm having trouble figuring out what'd be best for my situation!
Did you remember to add an emissivity correction factor when measuring the temp of the heatsink? If not, it gives too high value compared to polished, non-treated, brushed, painted or lighter shade anodized aluminum. Though the difference between anodizing colors is so very small (when the surface structure / porosity is identical) that correction factor isn't really needed. I like to use a surface temperature probe (with a multimeter) because it gives superior accuracy - but it's more time-consuming.
I had the same thought process that you did. The difference is very small. I did not adjust the emissivity - so the values that I measured may be slightly higher than the true temp - I figured it would be better to err on this side. Grower Love!
Hello, somebody order this led to EU ? on amazon with shipping shows me $ 175 and $ 0 for export fees to the Netherlands, but is it really, I will pay nothing extra to it?
This testing that you are doing now they did it already , results are in the same report you showed in the video YPF , is the test area readings. real field efficiency is 2.389, is a sting efficient little led that one you tested there
YPF is based on the Sphere test = not a PPFD or PAR test. In YPF you weight the different spectra ranges based on Mcree's research on efficacy. Both the Sphere test values (PPF and YPF) are based on Total PPF - a field test is different, we measure the Usable PPF. Grower Love
Define "better", a relative term. In this case the light out per dollar is greater for the Maxisun and Viparspectra, but it's hard to want to reinforce late capitalism by going with such a non-innovative and faceless company just for a cheaper product. Better in that the Maxisun and Viparspectra don't have included extension cords for remote placement of the ballast, making it impossible? Seems like they intend to run those boards hot by not giving you that option, degrading your LED output faster, and it will always appear bright to your eyes so you wont notice and surely can't afford a PAR meter to check if what you're buying are sub-$100 2x2 lights. Better in that their customer support is flippant and that they don't offer many technical specifications? Sphere test report? That little remote for the Maxisun is cute, just waiting to be lost or break. You can daisy chain the Hydra through it's digital dimmer and control it with 0-10v lighting controllers for sun up/down, temp-dim, etc. The Hydra uses industry standard RJ-45 jacks and can be hooked up to a Casambi or similar wifi controller for endless automation like 50% duty cycles for pulsed-light applications. Mike at Atreum is a solid engineer and communicator, so their customer support is top notch.
