well you could also look at the induction grow journal Solcielo did on another RIU forum https://www.rollitup.org/grow-journals/401594-blue-dream-800w-induction-lights.html which does what LED would claim at less cost per meter, long lamp life and a single lamp from veg to bud. Or you could just...

I just got mine in today and will start hanging them tomorrow. My first impression is I've never seen a lamp that looked anything like these before. They're huge and the glass walls seem thicker compared to any other fluorescent lamps I've ever seen. And yes I don't believe I'll need the AC...

much like the differences between a boom box and a high end amp / pre-amp, with high frequency drivers there are huge differences between driver mfg's and the phosphor blends they use. All I know is that I've seen 600 umole average/sqm at PAR uv and ir spectrums that do not require mated red...

In the interest of complete description of these ranges I could have said these fall between violet/ultraviolet and red/infrared but I expect that most of the people reading these forums already have an understanding of spectral wavelengths relative to PAR and human visibility. If not this chart...

I respectfully disagree. Looking at a light is no test. A purple light or a high intensity light to the eye means nothing to a plants lighting needs. For the most part our plants need UV (380-520 nm) and IR (610-720 nm) that are outside the range of the human vision (520-610 nm). So our...

I just ordered 3 of these lights today for a 4 x 8 tent grow I'll be starting in a couple of weeks. Hindsight being 20/20 would you recommend a wider spacing to move more light down to the lower buds? Other then a little ph burn (do you know what caused that? Was it the light?) these are...

Now I've got to try it on my next Kush blend and you got me thinking.... My grow buddy, I guess he's a hippie too because he hasn't really given up on the 60's, swears that the plants are still 'alive' after we cut them and they still if handled properly, will increase resins and oils. What do...

I wouldn't call it advertising. check out every LED mfg who has customers posting their vaious attributes on other forums. Unless you're selling them it's not a problem

I don't see a manufacturer listed so I could not see the spectrums being emitted. I would gather they are designed for the entire grow as a primary light source. Are these the same fixtures as being used on this journal or are they different technologies...

I was just on the LED USERS UNITE thread and Kessil is actually telling their customers not to run the lights when the lamps burn out due to the possibility of fire.I'm just wondering if that is an industry practice to be on the safe side. What would you do Cammie?

Kessil actually told you this? While they certainly have their problems I did not see any evidence of thermal runaway inside the unit that would lead to a fire. That's something I would have noticed and reacted to much differently. From all of the products out of China we see they tend to just...

I opened one up to see if it was something that I could indentify as a power supply problem but there is an inherent problem in the design. It's pretty much exactly what Chaz goes into in his next post when he hits on 'cascading failures' which affect mortality no matter which way the...

After my research I bought Kessil because I felt the product was best engineered for the exact spectrums I wanted to cover. Now I've got 4 Kessils that have lost led lamps after less then 4 months and I'm not even using them I've switched back to hps. Thanks for the article link. After...

thank you for this post. I love Tesla and while I've heard of this technology I had never seen it in actual use, much less for our purposes. Kudos and subbed.

I find it hard to believe a 400 watt induction replaces a 1600 watt HID. Post a spectrum analysis from the mfg so we can see UV and IR wavelengths and a link to the mfg website. thanks
