Testing Hans panel: 56watt Cree xp-e/ Lumiled rebel power==== Let's talk efficiency

Comparing the "footprint" to the size of the panel and throwing a bit of trigonometry at the dimensions and reflector angles looks like it needs to be about 3 inches above your canopy ... looks like a very close scrog will be needed to achieve anything except weak stretched plants.

... but, I'm subbed and willing to learn.

Well I would say that I have no idea on this panel's peformance from a personal experience, I've been using Cmh bulbs (philips retrowhite) for indoor lighting the last couple years, love the set it and forget it ideology, so this will be a first for us both I guess and I hope that quality diodes trumps larger higher wattage panels due to efficiency,,,,,,,,,,,but who knows really, i just wanna grow again and be open minded to the future(it will be someday/ you can quote me on that!) of indoor horticultural lighting........lets sit back and enjoy the show fellow grower.........ill try my best; that's all i can guarantee

Edit: Hans has told me that two panels are my best bet under my circumstances(he answered my email!!!lol).....but his website clearly states that it's exceptable use is within 24" x 20"inches, so fuck it I am pushing it slightly over(breaking out the creative training methods I guess) , and i'm not expecting any RIU member to burn 500 bucks on lighting 2x2 area; especially not over two autoshaha.....

Nice setup man, subbed for this.

Was wondering about the candles burning and releasing fumes which may stick to the flower heads? or am i over thinking this?

Peace to all, keep the happiness growing.

Good question............it should be alright using them, as long as their natural wax/parafin/oil no scents..........I'm only running them for 4hr a day/ will see how it does....

Of course green is amply covered in Cree Warm/Cool Whites as are other key spectrums like yellow and orange

Yeah maybe we can get Hans to wake up and stick some cool/warm xp-e whites on his panel

industry leading leds are an other story compared to imitations leds ... and the lenses talk take an all different angle

I recall an article abut paraffin wax candles. I think they burn cleaner/healthier than the el cheapos.

As to Hans using jumpers, it does minimize the cost v 3 different switches, and you only switch once each per grow, so no biggie
