I have tested them on 240V and they worked just the same I think @Greengenes707 runs his on 240V.
Looking at this chart, the halogen may actually be more efficient than the infrared LEDs and certainly a whole lot cheaper. I am not very informed regarding the flower initiation technique. I am still skeptical but I have not tried it myself and many of the DIYers that are using it are smart fellows so maybe there is something to it.
Good info CH. I agree that efficiency in this case is mostly irrelevant, but would the halogen do the job? Also, do you think it is the 730nm flower initiation technique is effective and if so, is there a possibility of any negative consequences of forcing the plant to sleep?
Im limited by neither space or heat, If im using Co2 ill have to have the temps high but that and side lighting are things work out once im set up.Are you limited by space or heat management? If heat is holding you back it make sense to run softer (~800mA) so you can create as much light as possible with as little heat as possible. But if space is the main thing holding you back, you could crank up the intensity (1450mA) at the expense of efficiency as long as you can move all that heat out somehow. You can run the Veros even harder but it requires the use of more expensive drivers, so an increase in up front cost without the bonus of increased efficiency.
I have been vegging the ladies up larger to try and increase yield (more roots, more fruits theory). Some of them have been finished 4.5-5 feet tall and for the most part I am using overhead lighting. So it may be a better use of space to work in some kind of side lighting on the outside edges of the canopy.
So would you incorporate them into the bar or get the flower initiator floods at 200$ each? If on the bar do you know which LED is the best choice and what about coverage?730nm leds make teh whole process so much easier though. You figure signals is one of the main original uses of LEDS (street lights, remote controls, etc)

this is a cheaper cooling solution that comes with screws for mounting.Im limited by neither space or heat, If im using Co2 ill have to have the temps high but that and side lighting are things work out once im set up.
So 1450mA? How will that effect the draw? Im roughly basing things on 60w per..Including driver-cooling.
Just looked at Arrow and ts said 100 in the pipeline but says April! Usually how accurate is the order page? I hope bore April or ill be in market for Vero 29's.
So..4 or 5 COB's on a meter long heat sink?...1 or 2 fans?

Anyone used this?

Thanks!!!
10 whopping watts of 730 nm FR ,for ~ $22 ...I wouldn't spend 200 dollars on a flower initiator. You can either use epistar 730nm or ledengin, unless there's another brand that makes high powered 730nm leds now.
I use ledengin... i forget what exact model, but I know the price went up. It shouldn't matter how efficient it is as long as it's 730nm, since it will only run for 5-15minutes at lights out.
You can get away with just using a long aluminum flat rod with 3 leds on it. That's what me and positivity do. (i copied his design) CaptainMorgan uses a rebuilt flood lamp of some kind.
Great info, i helped sell that 100 out, i have 20 x CXA AB's on the way and a request in for 40 more, not in a huge rush but ill keep the Vero's in mind. Waiting on 6" heatsink bars to come available.
Do you have more info on the Halogens as flower initiators?
Thoughts on bars vs panels?
Sorry but after all this reading im still wondering, with the intensity vs efficiency what is the sweet spot as far as GPW? I know some crank it up to make the buds more dense or what ever, Im not concerned with that nor on the other side driving the units too hard, im a total yield whore. Ill be doing one or two strains w C02.
not sure but I doubt a halogen will work as a "flower initiator" its got too much light in the 600-660 nm range to cause a quick and dramatic shift in the Pf/Pfr ratio. Probably only slightly better than just turning the lights off.Good info CH. I agree that efficiency in this case is mostly irrelevant, but would the halogen do the job? Also, do you think it is the 730nm flower initiation technique is effective and if so, is there a possibility of any negative consequences of forcing the plant to sleep?
CaptainMorgan would be the best person to ask, as he's got a few years of experience behind using infrared (IR).Good info CH.

Great, what kinda coverage with the ledgin?I

Yup, got 5 on order for my spotlight cobs, if i build bars ill only need 1 fan per 2-3 Cobs. My is my plan using 6" Heat sink bars from heatskinusa. You think im better off tacking Spotlight Cobs w/Attic cooers to Aluminium bars?i feel like the arctic 11 plus has become the standard for DIY led builds.
Thanks...I wonder about the coverage,,,10 W, This is the style i have seen before..Why i was asking about a lens to spread out the light.
Cheers, the price is right, What kind coverage do the provide? 2 per plant is a tough guide!CaptainMorgan would be the best person to ask, as he's got a few years of experience behind using infrared (IR).
