He says one side looking better but no actual data, input wattage to weight/potency. It's an interesting grow but not the kind of controlled study that I'd like to see.

Those cobs would be interesting to play with.

I added a luxeon sunplus rose cob to my rig but only did a single run with it. Cant say if it made a difference or not.

The lumious cxm-32 looks most interesting to me. 2.3 efficiency @ about 100w but such a nice spectrum: the red "tail" is really fat, high levels of 680nm. Citis plant white looks a bit more red shy.

In 2012 I was in a grow shop trying to decide on a light fixture to start indoor growing. I asked about LED and all they had were those individual lights..I can't remember the company....that were blue, red, or magenta. The owner said HID was by far the best. Just before I paid for my light, reflector, and ballast a guy brought in a ballast that had caught on fire and he was wondering about warranty etc. I left the shop and went home and ordered a blurple 180 watt LED and started growing.

I want both of them! I'm not sure how much red I need so I'd use the datasheets to figure out what currents to run them with the same output and put them in a cage match against white.

I'm starting to get an itch for those plant white CXM22s. I have a space to do a side by side with CXM22 in 3500K 90CRI. I already have the lamps, would just need to switch out the emitters on half of them. They aren't set up for dimming so I'll probably do that too. Use a kill a watt to get both sets of lamps using the same input... it wouldn't be a direct comparison of spectrum PPF vs PPF but it would be same chips with different phosphor which would be more practical anyway.

It would be possible to use the datasheets to determine the exact currents needed to do a direct spectrum comparison. I would have to dive back into the math and figure that out.

Maybe I'll do both eventually. I haven't stayed caught up on the industry, had no idea CXM22s came in plant white and blurple. Very interesting!

Using the same 600 watt HID ballast and hood I bought back in 2017. I also have a 1000 watt magnetic ballast. I have a 4 bulb 4 ft T5 that I still use. I also have a 100 watt LED that I was using but put my T5 back in the veg tent because it gave better coverage.

I have no need to replace any of my lights and will continue using them for as long as they work. Judging by some of the photos people post of their plants, just using LED doesn't make you a better grower or have healthy plants.

Use whatever light you want. Spending a bunch of money to replace equipment that's working just fine isn't something I feel the need to do. I'm not chasing technology I'm growing plants and the equipment I'm using does that just fine and with much less hassle of monitoring the values from some LED chart. In a small home grow like mine which is a 4x4 flowering tent the added cost of purchasing a new light is not going to magically improve my grow in any substantial way and with cheap power it would take years to recover any power saving costs. By then the lights people are paying $500+ for will be going for under $200.

Still tons of people on Insta using HPS. One guy is rockin bare bulb vert still. They argue with me about LED like it’s still up for debate.
Also, LED is just LED to the guy that’s still stuck on HPS. All the junk LED gives the good stuff a bad rap.

A dialed in bare bulb vert is pretty tough to beat. Would love to have the real estate to give one a shot

Cause led drivers / systems are so much more electrically sound than HID ballasts? :lol::lol::lol:

Interesting note about plant health and very logical :clap:

Really? People are stuck on HID's? All of us idiots using HID's don't know shit.

I have cheap power and perfectly functioning equipment. I grow in an unheated garage in the winter and welcome the heat from the HID. I've pulled 20 zips of solid bud from a 4x4 with my stuck in the past 600 watt HID. Can you give me a good reason why I should ditch what I'm using and spend $500 to replace it? Nobody's stuck in the past. There are lots of people using HID lighting getting better yields and quality than many using LED's. LED lighting isn't some magical potion. If you can grow you can grow. There are hundred if not thousands of posts from people that have invested a ton of money on LED lights that still can't grow a decent plant because they focused too much on buying the latest light and never bothered to take the time to learn about actually growing a plant and can't even water and feed properly or get a seed to germinate. But they have a $500 LED.

Thanks for that. Wonder why he is skeptical? I notice they both have red diodes. The Amare has blue as well. That makes it difficult to quantify what's actually going on, but it's a good advertisement for both Chilled and Amare.

The kind of study I'd like to see would include identical micromole output. I don't think that can be done with a regular PAR meter when the frequency stretches +700. I think there are meters that will take those measurements but they are expensive. It could be approximated using datasheets to determine the currents needed but would be nice to take measurements to confirm. And ideally it would be two identical white spectrums/identical emitters, one with added red. That would help determine how the spectrum itself affected the product. Alternatively, two different spectrums each running with the same output wattage would be practical/useful but not really answer the question of how spectrum affects plant growth. I'm not saying the kind of tests done in your link isn't worthwhile. It's good to see people doing it, and enough of such data might help form an educated opinion.

Also, I've been active growing but it's been a couple years since I spent time researching the lighting aspect of the hobby... so I might be a little behind the times.

I'm with you. I currently run 301H's with 660 nan IR. Preferred my lumitek cobs I sold. And the buds under my 1000W HPS were of top shelf grade. I get better densities now. No better over all beyond the light bill. And the additional head aches of getting the setting right to avoid so many issues.

The Amare also has UVA.
Thing is we are what 10 years later from blurple and the people peddling led's are still using the excuse that test equipment is too expensive?
Unfortunately most on this forum are narrow sighted and although this is a cannabis forum, try growing some other species of plants under various lighting techs and you will get an eye opener. :peace:

I'm aware there's been a lot of advances in product and availability, and that's great. Anecdotal and first hand evidence isn't useless. Thing is, comparing one brand to another isn't going to produce a scientifically accurate result unless you can quantify the radiation with precision.

I just checked prices on wide range par meters. A unit measuring 350-800nm is $3,000 and another measuring 380-780 is $1,500. Those are both better prices than what I saw a few years ago. Still too rich for me, but yes you need that kind of equipment to insure equal amounts of radiation. Maybe the guy in your link used that level of equipment? I didn't see where it was said.

It's pretty important, especially when it's a show grow pitting lamp manufacturers against one another. I'll have a lot less skepticism looking at custom rigs that don't promote anything but the radiation itself. And even though I'm a hobby grower I like that kind of precision when spending money on production units. On a commercial level, I would be hiring an electrician to install custom rigs, so either way I have no brand affiliation or care to hype a brand. My favorite brands are Luminus, Samsung, Cree, Citizen...
