Not quite, I'm saying livingsoilman quoted something from that guide. LeoLED themselves got the information from another source e.g. Wikipedia or other as I can see their copyscape percentage. Companies just rephrase these things in their own way. Again, theory is nice but proof is better.Lol... at least they know what they're talking about.
Would like to know this as wellI'm totally new to grow lights and decided to go the DIY route. I ordered 2 Vero 29 4000K COBs and a MeanWell HLG-185h-c1400b. I know this driver will power 3 Vero 29s, but I only want to run two. Will it blow them or will it be ok? Thanks for any advice you can give.

The proof is in the pudding. Knowing proper information goes along way. Only companies that know what they are doing post information as such.whats funny those cob lights you mentioned dont even provide the ppfd. The most simple reading . Wouldn't trust a company that dosnt even provide that.(probably dont have funds for such test or equipment) You cant just make a cob light and say its 200w without providing proper readings. 200w actual draw from wall doesnt mean squat without proper ppf and ppfd reading. Please steer away from any company with vauge spec information. The less they provide , the less they know about horticulture lights. Atleast those companies take time to inform the customer then mislead them with vague and non specific information.Not quite, I'm saying livingsoilman quoted something from that guide.

I'm at the same stage you are. Waiting on the answerdo you know the answer vice? can anyone help -- I'm in the middle of wiring -- do I set fans to blow air onto the heatsink or pull air from?
Sent from my SM-G900T using Rollitup mobile app
Pushing/blowing works best at cooling, especially in open air. Pulling can be effective with shrouding. Examples in real life: cpu cooler fan pushes towards heatsink, xbox360 pulls air through heatsink and out the back, graphics cards push air through ducting across heatsink or push straight on.I installed them blowing onto the heatsink dunno if they are right.. below them on the other side are 3x 3590 cob cd bin under each 80mm fan heatsink measurements are 3.75" w and 36" length with 1" fins base thickness is .3"[/QUOTE
I'd be much more likely now to buy a light like plc or tasty from people who advertise openly here and are wide out in the open for their criticism numbers numbers numbers numbers numbers. ..mean nothing without results are pretty much meaningless, just look at the different ways it's being done.The proof is in the pudding.

Alot of led companies dont know about rollitup. Pretty sure I could get leoled or any other led company on these forurms its a matter of asking. And alot of the big players have tons of resources(money) for research and development. So the fact they take time to tell me how a light and par, pff, pffd, DLI matter and sorta explain "physics" mad props. Most companies are vauge and dont give you info at all. Im all about education on the consumer part so we dont end up buying shity lights. Maybe its time people start reaching out to these companies and let em know to get on these forums......I'd be much more likely now to buy a light like plc or tasty from people who advertise openly here and are wide out in the open for their criticism numbers numbers numbers numbers numbers. ..mean nothing without results are pretty much meaningless, just look at the different ways it's being done.
I say this after having bought a Shenzhen light. Then based on what I've learned here from the manufacturers of tasty and plc no less, have been able to produce 180 watts of quality light vs the 200 watts of which a high percentage was heat from a light that was advertised as 400w. Just because they blab about what makes a good light doesn't make then a good light manufacturer.
I don't disagree and would encourage participation from all. Like you said there are huge companies out there with rooms dedicated to measurements I'd like to take advantage of that.Alot of led companies dont know about rollitup.
