I think you meant to use 240? (HLG-240-1400) prob more accurate to use Watts law though: watts=voltage x amps ... 108v x 1.4 amps = 151.2w (prob slightly higher with driver overhead, also Meanwell drivers often operate a bit above spec)

Thank you for making this. Going to give it a try. To all the ios people out there: Try to get it through your heads that there will be no apple version. If you want to try it get an old windows machine. there are millions of them out there you can get for $50 or less or even for free, Its...

And yes, it is safe for the cobs. When you wire them in series they just take what they need.

Absolutely not. Most people building flowering lights are going with 3000k. Some slightly lower, some slightly higher. If they're vegging with it as well, some choose to go 3500k. There are a few people flowering with 4000k, but I think most would say that 4000k has more blue than is ideal...

Yeah now that I look, that driver tops out at 39v which will get you to around 2700ma. If you wanted to burn one of these out you'd have to step up to the 42v or higher. If you ran it at 39v for any length of time you would probably fry the chip though, since it would require very robust...

Yes, when you had only 1 hooked up you were putting all that juice through it. I'd be surprised if it hasn't been damaged. The only way you'll be able to use it with the 2 cobs you have is to get a potentiometer and dim it down.

They look cool, but if the specs are correct... 15w and 900 lumens would make them pretty terrible.

I don't. You seem to think it doesn't make much sense for them to have Canadian resellers though. Anyway I don't know why you're debating with me. You should be arguing these points with HLG. I don't even own any of their products :)

Am currently putting together a few fixtures. Was thinking of using clear silicone for this.

Then I suggest you have a chat with Stephen & Robin about their shoddy business plan.

http://www.grandmasterlevel.com/ has the first 3 seasons (youtube seems to delete his stuff every so often) In the latest episode he and @Stephenj37826 talk about how he has already received 1 shipment of product and that the next one is on its way. GML goes on to say that he has secured the...

That's pretty much like saying you don't need to know how fast you were travelling to calculate the distance you traveled. "We traveled 4 hours, how far did we go?" ummm... how fast were you going? :) So to calculate DLI you need to know how long the lights were on, and also how how intense...

This whole thread is about being able to buy things in Canada. So the same benefits as anything else you would buy here instead of importing from another country. Pricing I am not sure of, but quicker shipping times, cheaper shipping, no duties (obviously something will be included in the cost...

GML is this guy: https://www.youtube.com/channel/UCDY8sQMuA9Hfx_5w-8J4afg/videos Stephen from HLG is now a regular on his show. Not quite sure if that's forever or just while the hps vs quantum side-by-side test is ongoing.

Starting in a week or so from now, GML will be running a Canadian website for HLG's gear.

When you say 1000w, do you mean an Amazon led fixture that is really 200w or so? If so, the led bulbs are probably better than the main light.

There is no one name for lights like this, they come from Alibaba and are sold on Ebay and Amazon under any number of names. Your light probably pulls about 100w from the wall but might be advertised (lied about) as anything from 400-1000w.. They use cheap old-fashioned diodes that are not all...

When I look at the numbers the thermal resistance is extremely high on the tape

Thermal tape is garbage compared to actual thermal pads (like by a factor of ten). Prob ok for most strips but not for cobs.
