Cree led grow lights? - LED Grow Lights - International Cannagraphic Magazine Forums

hey guys,

i make my own led grow light using cree chips and have been using them for the past couple years now. anybody see the new led lights available from that dutch guy on ledgrow,eu? hes been playing around with led exclusively for the purpose of growing marijuana for the past 5 years, most recent harvest was 153g for 112w of led light. hes selling his own lights now but its $240 a pop plus $50 shipping for 60w cree XPE. his 60w claim 35% more light than 90w chinese ufo.
Which reputable led dealers sell cree made grow lights for relatively affordable prices. i keep seeing and hearing lots of good things about the blackstars from light house hydro. would they be one of the best to get? I want to see if i would save time and money buying premade.

thanx.

wow guys so much for asking whether any of you think im better of building my new flowering panels even though i dont have too much time currently because of work. or would a prebought system from either ledgrow.eu or gotham hydro that makes the blackstar be any good? all 3 options would end up costing me around the same. have to go to flowering in a few weeks and want to make sure have a light ready.
thanx

Yes you can have the CREE LED grow lights which you can get in reasonable prices also they provide high lighting sources with more safety performance. There are different models of CREE LED lights available in the market based upon the prices which are more reliable and durable.

didn't see this till today. maybe a mod moved it into here, it's kinda hard to find this sub-sub-sub-sub topic

I started with the blackstar and I'm done with them. They are alright fixtures but they dont seem to be as powerful as others out there. The real problem is that they are @ 130w instead of 240 like they claim. Had a 500 but a bank of lights went out and had to return it. I opted for two 240's in return in order to space the light out, but also when i was testing it i noticed that the heat sink is just a sheet of aluminum, not finned like it needed to be. so the larger fixture seemed like it would have more of a heat issue since it's got a higher concentration of led. Also, the clear led cover looks like its made of plastic, and starting to show white spotting from the heat/light. I'm switching over to the diamond series from advanced led.

I have a 400w diamond series that seems like a much sturdier light,finned heat sink, larger quieter fans, glass led cover as well as much more powerful. it's pulling 390w, which is exactly 3 blackstars. @ $950 vs $900 (for three blackstars) your not saving that much money buying the cheaper equipment, your just buying it one piece at a time. realistically though, 3 blackstars at that price are overpriced. Buy one at most just to get started, especially if you plan on ripping it apart when it breaks.

led is an investment, know that, and realize that the cheaper equipment is not worth it in the long run.

yeah, whining won't get you far in these parts bro, ...why not actually do a search here for LEDs as there are several here who are quite knowledgeable and would gladly help you if they knew you needed help.

and you can't go by how many views you've gotten as all those who have viewed may be noobs.

I'd stay away from from the china panels, blackstar, HGL ect, they're not terrible, (they'll grow good bud for a while) but they're expensive, use cheap components, noisy fans and generally burn out far faster then they should.

Most panels using top binned CREE leds made in the US or EU are expensive, way more then they ought to be.

check out; mouser.com, rapidled.com, ledgroupbuy.com, for pricing of components

You can build and customize your own light pretty easily these days ( hint: BJB solderless connectors) and have the ability to easily upgrade as better leds become available.

Also dont rule out the combination of led and HPS, something along the lines of 150 HPS and 50-100watts of Cree XP-E 625 and XT-E 455 Royal Blue. This would provide you with a very complete spectrum of light.

hope this helps

I know Diamond Series is producing a light that uses 3w Bridgelux diodes for their colored spectrum and Cree 10w XM-L for white light in a single unit. The specs say the unit runs at 135w and it is a 12.5" x 12.5" unit. The cost is a bit high at $549 but its a unit I would absolutely buy if I had the money for it.

I have been looking through the Cree site to try and figure out what it would take me to put together my own unit. I am really interested in the XR-E diodes. They run at 4w and offer three different types of white light , but what really excites me about them is they offer a 90 degree light spread. From what I have been seeing in my LED research is that a spread of 90 degrees or less is ideal for growing.

I just ran across a grow light that uses Cree's, here is the manufacturers site: https://www.bysenled.com/led-grow-light/h158d-140w.html

It's retailed by others (some with a 5 year warranty!) and seems to be quite new. I was originally thinking it might be a flaky design but then I saw a few posts and web pages showing people are starting to think they are the way to go.

Only problem is that they don't give the spectrums of the outer led's around the Crees but they are Bridgelux according to one source. I'm trying to pin it down now actually.

Can you show us the other places you found those units. It appears that bysen is indeed in china, so I am not sure exactly how good those units will be, especially because there are no real specs about the product on the site.
