I replied your pm. In order to avoid any problem take type B driver.At full power you will be 1050mA with no problem of overdriving your strip.But use hlg 240 c1050 for 5 strip.Is the best choice for you

No. Test was 1 board vs 4 cob.Same watt from plug

Screw is all you need

you need to plug driver to AC-plug. I am sure you can save money with semi DIY kit. Cob already mounted on heatsink, maybe you have to plug few cable more(even my girlfriend that is super noob was able to do it). EDIT 200watt for 316€ (£280) is really expensive. You can get 2 board for 160€ and...

I am actually using 1 board in a 60x40cm small tent at 100watt.No problem with airflow or temperature.Fixture is 33cm from canopy

Hlg-480h-c1050 does not exist But 320,240,185 etc exist. I do not know prices in US, but in Europe the most convenient driver for you would be hlg-240h-c1050 A You can drive 5 strip of 46v with 1 driver.Type A model has also an overboost on output current so you will easily have a max output of...

Seems pretty expensive.And you still have to wire with wago.So almost like a semi assembled diy kit you can purchase for much cheaper price.But choice is yours :bigjoint:

Take a look....if you want to try diy you can find board or cob http://www.flowerpowerbologna.it/epages/99883.sf/it_IT/?ObjectPath=/Shops/99883/Categories/Illuminazione/LED

I made a comparison with 4 citizen 1212 gen 6. Board and cob same height and watt at wall from same driver.Took 29 point grid mesurements. Than I made addition of all ppfd from each point. Total for cob was 19149 Total for board was 19718 EDIT: Did more accurate test about passive cooling...

I have seen prototype at a cannabis equipment exhibition on may 2017, so I do not think so.He tried different layout and also different manufacterer before he finally release.I know him very well... I have been asking about it since May.I had a cob fixture and wanted to try quantum board but...

Sorry, English is not my mother language and I have not enough sensibility with its vocabulary to read humour if it is not clear enough:bigjoint::bigjoint::bigjoint: BTW you and few other member here are the most reputable person so I always read your post, but like lurkin more than posting

I think it has hole position ready for 120mm fan but I need to ask. I do not think seller has copied you, he is devoloping his project since may 2017bongsmilie, it's just a coincidence. Please do not sue me:bigjoint:

Connector are no soldering, push cable in and it's locked.Push on connector to release.Up now, no heathsink at 1750ma.Temperature is around 50 degree (used a thermal gun). Seller is still tryng to find the cheapest solution for heatsink (hlg style heathsink will be too heavy and unconvenient for...

I can only take picture with phone:wall: There is no visible black dot I am quite sure about chips anyway, since seller posted original samsung packaging with bin written on it

I like also passive cooling up to 1750ma

yep!342 chip. 2 different model: 1 full 3000k, 1 mix 3000k(270pcs)+5000k(72pcs) I got both Board should be on point with hlg, since it has even more row in parallel (less current for each chip at a given Amp)

After long waiting I finally got my lm561 boards without having to pay crazy amount on shipping and tax duties:bigjoint: Since I have been in contact with seller, I had the opportunity to test it as soon as he received board and got 10% discount ( I do not have any affiliation , just got some...

Hlg-240h-c1050 A is the answer. Type B is very strictly limited to parameters while type A is not.I tried several type A and all of them got some extra current. C1400 goes up to 1670/1750ma (range between model) c2100 goes up to 2400/2600ma.If you take C1050 you will have 1120 for sure

You are about to live something that many people can only dream, here in Europe. Hope the best for you✌✌✌✌

I should receive board for testing around 7 of January. Told to the guy who will sell it about interested people from Europe. Maybe he will allow me to link his shop sooner, but he want to be sure board are within spec, before doing this.BTW, it should be 2 oz copper, 342 lm561c s6 az bin...
