LED Lights

A Bloke Down The Pub · Mon Feb 09, 2015 5:36 am

I've been thinking about experimenting with some "single chip" 100W leds this year.
Main problem is sorting out a driver.. they need around 30V at constant current, and I don't have a suitable PSU at the moment.
I can drive one at a time, but I'm thinking I'd like at least three per lighting unit.
They're available in colours, but I reckon a "cool white" will do quite well for vegging.

They'll also need a bit of heatsinking... may need to rip an old PC or two down.

I've found any light source that looks reasonably "white" will work fine for growing if there are enough lumens. I in fact did fine for years growing starts for transplant under cheapo 48 inch, 89 cent "shop light" fluorescents. Carefully tuning the output wavelengths might buy you a few milligrams per watt of efficiency, but at what cost in time and money? Good enough is, as ever, good enough.

The dx com is purty good inexpensive DIY site with inexpensive LEDs, one like the pic you posted above @~14$, and drivers, power supplies and more led parts for the DIYer.

I was thinking ya could by use LED bulbs that are ready to screw into a standard light socket. make a panel of say 50 of these (5 x 10) for a 350 watt panel similar to one my fluoro panels. No need to hassle with drivers or step down voltage regulators.

7W 6500K White LED $4.59. Available in 6500 K or 3000k. Alternate them for a good plant spectrum

I have been using that very lamp in my desk light for about a year now, for 7w it is brighter then the 23w curly floro bulb it replaced.
for whatever it is worth.

interesting...

ive a client who goes in for the good stuff
bought some led floods for him
damn things cost nearly 50 bucks!

supposed to last forever though

he had some outdoor lights in places so high up
it would cost him 200 bucks to hire someone with a tall enough ladder who'd drive out to the remote local

heh

i put myself on a leash
and hung off the roof to swap em!

id a tarp over a couple sawhorses below
spread out like that firemans rig
for catching people jumping out of buildings

just in case i dropped the bulb

probably not the smartest thing ive ever done

these days im flat bust
figured building an array would be the most economical avenue
given i cant bump the electrical bill here much

but i will definately compare my parts list with those bulbs
hadnt even though of doing it that way

thanks!

All my grow experience says. Outdoors is risky. I end up falling back on my own seeds to have anything. Seasons come and seasons go. Hot cold. When I invest in a seed now its indoors. In winter less heating costs. So in summer there will be no outdoor grows due to several things including a new neighbor moved in nearby.

Empty for years.

Growing inside is the best way to go. Control of the environment if you have the money. AC..

A good LED would not require me to install an AC

If it would grow big buds. But it won't yet right?

Im not a scientist and I didn't vote for Bill Nye the Science Guy I'd say there is some people promoting their selfish motives over the best thing for all humans in the world.

Don't exagerate and over advertise what your product can do.

And you will gain the trust of your customers.
