Lost In The Fog

If I had more time I would do something like that ^^ then u really know what u got ;)

You got to put an limit to what you should make with your time. Those boards/strips are just chips in series. Try arduino:ing a controller for them. Seen lights with dawn, cloudy and sunset programs. That would be very cool. Mixing 3000-5000ks with some deep red diodes and controlling them with a program.

Seems hard to find a good seller in europe at all :confused:

Yeah, I agree you on that. Everything here is stone age stuff like Apollo lights for hundreds of euros or a UFO light 75W for 99 euro. It's a robbery. I wounder if they even sell any.

I have ordered all my highend stuff from the states. Sure it costs a few bucks but it's wort it. Getting stuff you know are good and at a decent price compared to the stuff we got here local in eu.

The most costly isn't the leds, it's the drivers. Maybe you should look in to that, building custom drivers. But when you got them you can easy buy new leds and always keep up to date with the new high end stuff.

Thats also an idea but with the COB's which are on mains u cant dimm them unfortunately

Making own drivers is...way to complicated, really - thats not easy ;)

Btw...found this NICE Osram LEDS - just as my COB's no driver needed, and they have ~102lumen/watt, whats not bad at all...drawback - they cost a lot :(

No of course. I meant if go buy some strips. I would order some stuff from your local German supplier if I were you.

Yeah, they are complex. Lots of odd stuff you hardly have laying around. :)

Forget those bigger cobs. You get much better spread of both light and heat with these mid power diodes.

ORDER NOW! ;)

They had just small ones and very large Qb style boards and none fit my driver as good as these inFlux ones. Now I can parallel wire them two by two and the two pair in series to match my 48V driver. There is a little shortage of Amps but I don't care if they are like 10-5% dimmed.

This is why I am tempted to just order what Rider wrote up for me. This is all meaningless when read it! I'll take up the conversation in my thread when I get home...short day at work because Thanksgiving is tomorrow.
 
Sorry it's german, but u see the data of this - it's a 50cm strip of aluminium with 98x Samsung LM301B - cost about 16,90€

I REALLY consider to buy them for the next grow. What do u think?

No the L09 has just more Watts ( has 2 rows of the LED's)

No it's for making wormholes to this site. :)

No, get 3000K!

The higher the CCT, the higher the electrical efficiency.
The lower the CCT, the higher the photosynthetical efficiency.

AKA the redder the better :) Since the difference in electrical efficiency between the different CCT's is low when using high end Middle Power Diodes.


3500K is a WORSE start to finish than 3000K, you sacrifice red for blue, or in reality a few hours shorter veg for less bulk and potency ;)

These strips are availible @ 3500k and 6000k - thought about 3 of them 2x 3500k and 1x 6000k and in edition again some red/blue one's (or others) - still not sure. U get also some strips of Cree on this site ... also in blue or red ...:hmmmm: may take some time to plan that :D but I think this wont be bad

Deep blue, never heard of that before. I think you should stick to these Samsung chips first. Then you can start experimenting.

These LED's are made for plants - and I dont think that Osram lies....

Horticulture Array with Osram SSL 120 look look @ the Osram page

just want to add them to the strips, to support them.

Yeah sure but those are red! :) Get a light that's good for all round growing. Like 3000Ks. With those you can both veg and bloom. There is no good bloom with deep blue or good veg with deep red.

Just got conformation from UPS and paid my tax and customs fee. 20$ so I paid 80$ for the lights. Get them on Monday. :yahoo:

These "fullspectrum" COB's or LED's are nothing else, just red and blue leds ?!

Yeah, but the 50cm strips I would get are only available @ 3500k and 6000k :(

I don't read alot but I did see acouple plants... And is that your light being water cooled in that pic? If so means you got her working? I hope I don't sound strange,,, but are you going to need it in the winter? JK But I do see the light,,, how is she working?

Ok. 3500k works but you get better bloom light for your money if you can get the 3000k instead.

It's ok. In this lost fog there are no strange questions. :)

Yes, the lights are water cooled. I had this idea in the crazy heat wave we experienced here this summer and this is the result of that crazy idea. I could sure cool them with heat sinks but I don't got any of those fancy pin fins. If I would have ordered them from the states, there are no 140mm on sale in Europe, I would have had to pay over 80$ just for the shipping.

I initially had them mounted on a aluminum sheet but the cooling was not sufficient and I burnt one deep red led on one of the lights so right now I don't got any thing else to cool them with. It sure works fine. Water temp at 30C and tent temp 23C.
