I don't know if I mentioned this before.

Like many of us, I have 100 1w led bulbs around here that I've made lights from. I've gone 5w to 20w arrays.
Then I came across these a year or so back.

SMD's

The first one I used, I was shocked by how much light!
It was a 10w SMD, but was brighter than the ones I've built..
So much so, I haven't gone back since.

Now, on my bench, I have two 40w equitant running (use 6w each).
Seems low aye..
The one I purchased you can take the lens off and expose the SMD!
Since I house them in those 'spot light' globes, I never look at them directly, but the increase of light by taking off that globe..

Immense!

If you decide to do the same, take care to insure you will not see the SMD!
That is, unless you like those dark spots in you eyes for some time..
Go ahead, ask, I tell you how I know.

The 40w equitant is closer to a 60w with the globe removed.
I have two of these, 4ft apart, and illuminate a good portion of the bench.

Still attempting to tune them in to the Super Joule Ringer, but on Mains.. 4cents a day to run.

I like them!

I got hooked on power emitters when I started catching up on flashlight forums
and they have really come a long way.

Right now there are a few that are supposed to be the most efficient out there, but I believe the Cree or Nichia emitters are the best.

Cree XM-L2 emitters of the newest bin and XP-L's which are the same thing
but without the little focusing domes.

They are rated for a max of about 10 watts. @roughly 3.7v 3A they put out 1000 lumens.

the chinese knockoff 10w and 100w emitters are cheap nowadays but they are not quite as efficient.

I've got an XHP-70 emitter in one of my flashlights, it takes two 18650's in series
pulling just under 5 amps, that thing puts out a blinding 5000 lumens lightweight in my hand lol.

Hi ODR

How are you coming with this project? Do you have a good SMD that works on lower voltage? Like 3.7 volts?

Haven't broke the 6w curve...
