Hi guys, I'm AtterStiga, and this is a combination of planning and getting through the wait for my cxb3590 kits to arrive. With what will replace one of my 600w hps in the flower room on the way, and nothing to do atm with that project, I'll just turn to the next. I have never had the space for a veg room before, but that has changed now. I'm tired of the boom and bust cycles in this availability of ganja, so now it's awn.
Since I don't yet have a dedicated veg light, I'll attempt to build a cob light for targeted frequencies and dimmable modularity. The Cree cxb2530 @350 or 500mA is probably my favourite contender right now, but I'm definitely open for suggestions. I've seen them built with single heatsinks, but I think I'd rather build with separate pin heatsinks like the Cutter kits, only smaller, obviously. After gaining a deep albeit theoretical understanding of the workings of cob lights, I predict the sourcing and gauging of heatsinks to be the biggest problem.
First questions: when dealing with thermal resistance, are we looking for a lowest possible number? I suspect it is, but the Wikipedia page looks kinda like something that should be on the walls inside a pyramid in Egypt.
Does anyone know if somebody already made a list of of bins on the different Cree cxbs? Like a spreadsheet? I can find out by looking at spreadsheets, but it's always good to get the opportunity to love somebody else's work lol.
I realize that the individual heatsinks might be cost prohibitive in the numbers we're speaking of here. In that case I would be grateful if somebody knows about a good source for extruded heatsink bars, preferably in Europe. I can imagine those babies rack up the shipping cost.
I might just go for a cxb3590 kit in whatever K is best suited for vegging, but it's a bit of an overkill. And I do believe that the cxb2530 or something like it would be great for the culinary herbs I've been planning to grow for ages.
If I end up doing this I will definitely post the build. I'm just assuming that the factors influencing a big cob light are the same with a small one. Of course, small as in smaller cobs, I'm one of those people who believe the babies love plenty light in veg as well. If anyone has information regarding ill effects of radically changed spectrum at the switch, pls shout out.
Just realized I have built a wall of text here, so it's a good time to end it here. Link me to some heatsinks if you know about any, all constructive input is appreciated. English is not my first language, so sometimes it's a bit hard to google effectively. So please bear with me.
Come on, lets explore the possibilities together. Gonna be sweet.
