Lighting TOPled The Manual.

You think there pricy check out these badboys....http://www.budmaster.co.uk/budmaster-ii-1200-god-led-grow-light.html using some high end chips though which is nice to see.

Phew, very pricey and I'll agree they are high end chips but I'd love to see where they get their claim of 200-300% more par than traditional leds!
Osram InGaAlP thin film is brilliant and has been around for a long time but I've yet to see anything from Osram themselves claiming anything more than a 20% improvement in efficiency. Any idea which Osram chip range they use in the budmasters?
 
The term "small" is definitely subjective. If I recall, you were growing in a tent that was a square meter, right? That converts to about 10.76 square feet. This means that you're getting <30 watts per square foot. I used the same panel, but in half the space at 5 square feet which yields 60 watts per square foot. That's a huge difference, and you may need more light.

Also, I noticed you only had 46" or 30" (couldn't tell which from your first journal post) of vertical space. My limited experience tells me that these 5w panels perform best pretty far from the plants. My first time growing, the plant came out short and stunted (huge buds though) because I kept the Mars II so close to it, sometimes even 18" or less. But on my current grow, I started with the light 45" inches away from the soil line and the plants grew much larger. Currently, just the main colas of the plants come to 24" away from the panel and they are growing some really nice buds.

I got your specs and information from the first page of your journal, so if you've since changed these parameters, just ignore me.

Hi Dr. Frog, Yes short might be a better term. My grow space is only 45" tall. I now have 25" of vertical space from the top of my res to the bottom of the light when it's hoisted all of the way to the top. My hydro unit is a single, eight site DWC centered in the tent. I'd say that the limited amount of vertical space I have to use is my biggest challange. Ultimately I am only trying to grow a couple of plants at a time so they wont occupy more space than the light will cover. I tried taming the light with a diffused last grow but I think I still saw some negative effects from the proximity of my light to the tops of the plants. I am building a SCROG screen for this grow hopefully it'll do the trick. Thanks
 
Man those Purple Alien panels are expensive, especially for 5w bulbs only running at around 35% power or 1.6 watts. I'm sure most 3w panels run at the same or more power through each bulb than that.

Here's something I've wondered about. To me, what % the bulbs or diodes are run at isn't always a great indicator of efficiency. I've read that LED chips have a "sweet-spot" when it comes to how much power they're driven at. At this "sweet spot," you're getting the best ratio of light for energy consumed. Anything higher than that % will make more light, but less efficiently. It's like diminishing returns. Driving LED's more closely to their maximum potential isn't as efficient, it just means you run the risk of them burning out, which warrants fancier heat sinks and fans. The way I understand it, it's better to have more diodes tuned down to their optimal power %, than it is to have fewer diodes that are driven at high power %.
 
How I howl with laughter at the poetic licence used by whoever writes led sellers web pages, do they think we don't have google?! :grin:

"200-300% more par than traditional leds! " I'm with you, anyone who buys into this BS needs to do a little more homework on the nature of LEDS. And increase of that size would be news worthy in the scientific community. LED grow lights continue to get better every year, yes. But thats an incremental increase, not exponential. 10% very believable. 20% possible, if coupled with a developmental increase in driver efficiency, but on the edge of credible. More than that, its complete and utter BS.


And for $4500 I could buy a 100 acre farm in Guatemala.............

Decent quality 3w/5w bulbs run most efficiently at roughly 55% to 66% of max power input. Combination of energy in/light out/bulb lifespan.
I'm a bit cycnical when I see these blatantly underclocked panels containing the "best" chips, it just translates to me that they've screwed up the design, they overheat or they've stuck cheap ass drivers in there to save money.

It's a bit like when apple claimed to have the fastest graphic card ever in a laptop, being intrigued as to why apple had bothered when they usually stick crap parts in a shiny case and spend the rest of the budget on advertising, I had a look at the spec only to find they had put the card in there but hugely underclocked it 'cos it would overheat in seconds at full power. They hadn't lied but nor had they told the whole truth :)
 
Hopefully my Led arrives later today. Track n Trace says its already in Germany aproax 2,5-3 Hrs ride from here. Wow was really fast 2 days earlier then estimated delivery Time. And that from China....... i really Start Liking this Company more n more.
 
It's the waiting that's the worst medi! :)
 
Oh yes like one of my fav German rappers always says .... i dont have a proplem with weed i only hate waiting on it..... same i feel with that Led right now Bilbo. Common Fed Ex yoe really want to deliver it today Looooool
