The key with led is to design your grow room for it and not just replace the lights. Start by moving the heat from you leds lights to your plants. Instead of sucking air from the top you push your warm air from the top to the bottom and suck it away from the bottom. It doesnt matter what...

Amnesia haze is a cut only strain, if you ever in amsterdam go to marnixstraat 90 this is a where you can get it. Otherwise is just weed called amnesia. Bassman try the jalisco jaze from sannieshop thats a good haze, sannies jack has nothing to do with haze.

We will see soon enough hard numbers from the 1825 I hope you are right and the citizen has the same ore better g/w ratio then 1.5. I dont care about companies brands I want to have a fixture that gives me the best g/w ratio If citizen does that I buy them.

And at 50W whats the lm/w ratio ? Anything below 180lm/w you can give it to Willis. Sorry but the CXB3590 is still king If you want a 56+ effi% fixture. Ooh you know that Citizen has a 10% tolerance ? You builded in may a citizen clu48-1818 at 700ma when are you going to give us some real...

Hmm why would somebody switch to led ? If you like to run 1g/1W I suggest you to use HPS much lower costs and allot of systems are build around It. The same go for these Citizen chips yes the price is good and the lm/w ratio is oke but its one step back and since the cxb3590 price has dropped...

Indeed very interesting I am also have a order for the clu48-1212 but going to run them on 700ma since one kwh is 0.23ct here.

Hmm let me see we are on a sub forum specially for LED and we are talking and comparing 2 Citizen COB leds of the same generation and family so 400W of what do you think that I am talking about ? I am out because you don't want to understand it and we are on a different page. Ooh and btw...

Yes I thought that you and jorgegonzales and bobby_g are smart ppl an you can figure it out but NO so lets explain it one more time. So this thing started when I said : ''The 1212 will win from the 1818 from 1W to 36W then the 1818 will get ahead, but the 1212 costs also 50-60% less then a...

Talking about ampere, Watt is for hps :) For example you want led fixture that runs on 700ma and will cover 1m2, you say that the 1818 fixture will be better I say no. you need either sixteen 1212 cobs for 170 euros Ore eleven 1818 chips for 240 euro.To cover the 1m2 space now pleas don't tell...

At 700ma 1212 = 24.2w the 1818 = 35.4 thats 31% more power from same ampere. The 1212 costs in my country and yours 2 between 10-12 the 1818 start at 24. Yes yes :)

The 1212 will win from the 1818 from 1w to 36w then the 1818 will get ahead, but the 1212 costs also 50-60% less then a 1818 and only have 1/3 less power.

Hello guys I have a question I remember to read a post here on the forum but cant find it anymore. It was about dimming leds and how it works, So what I remember is that dimming a cob is a bad idea to win effi% for example you have a hlg185-1750 and you are running it at 1.75a you change your...

Hey guys whats up cxb3590 3500k CD bin dropped in price ? Last time I was looking on cutter it was 44 euro for me and know 36 ? Maybe becouse the new Bin is out ? Good times :D

I bet you will even breath more when the price of the gen 7 comes out :)

Bobby_g Great work men can you do a 1212 3000k cri 70 ? I think thats a very good flowering cob

The price will make it ore brake it for Vero the new vero 29 gen looks good. If its costs 35€ that just to much a good price would be 25€ for the vero 29 and 15€ for the vero 18

Can we agree that when you using 1000w of cxb3590 @1400ma and 1000w of cxb3590 @700ma you need the same cooling power for the space ?

will those work ? http://nl.mouser.com/Search/m_ProductDetail.aspx?Cree-Inc%2FXPEFAR-L1-0000-00701%2F&qs=Rt6VE0PE%2FOeUVLT3F7NPxQ%3D%3D its the new gen xpg3 and shipping from the EU.

Yes my friend on one cutter 400watt-1050 driver. It will drive 11 of them.

why not close to the corner ? Sorry never worked with this things before. Why not run them seperate ? pretty hard to find a passive heatsink for 37.5watt for 5€ Ofc when you run them all alone you get better spread. But remember those are not cree chips and run lower the spread is going to be...
