I wonder if they get dimmer over time like most cheap Chinese leds.
I just received four
PICS AFTER INSTALL.
It'll be a little while - just realized the transformer I'm using to drive the current LEDs would be overloaded by about 100% with these, so I've got to cobble together a new power supply.

Hmm. I wonder if that is more prone to happening if they're driven harder. These are marketed for automotive use, where the voltage is in the upper 13s, but I'll probably be running them at 12V. The difference in heat output is not insignificant between those voltages.

Yea, I'm using 12V and I did go up to 13.8, and as expected they get hotter and brighter at 13.8. 12V is plenty bright for my use.
My workspace:
Oh man! I see all sorts of fun stuff there!

Cobbled together for sure! I present to you the Best Buck Converter Ever:
I've been working this whole weekend on my little corner in the basement, made the table and all the stuff around it.
I thought about putting shelves on the wall but apparently the wall itself is made antirely of cement and rocks, which makes drilling through it impossible.
The light looks bright but it's just a 15W tube.

Why can't you use a masonry bit and install the brackets with some sort of
metal expansion anchor?
Concrete means go borrow a SDS drill and make the holes for steel rod ( 12mm diameter) and put floating shelves up.
Yeah, i have one of those hammer drill things ( forgot how it's called in english ) mine's 1200W i just need to find where my brother put it.
I tried to do it with a standard concrete drill but it won't go any further than 1 cm.
Now i need to save up some more money for the angles and screws and such ( being a 10th grader budget is quite low ).

They are called hammer drills in English.
As per the depth, did you hit reinforcing steel by chance?
The SDS drill illustrated above will go through steel reinforcing, rock and such quite easily. solid granite boulders however do take some time to drill through, you are drilling through some of the hardest rock on earth.

I read
Refrigerator's post as only a standard drill has been used thus far, not a hammer drill.
As per the material, I wasn't thinking of granite (or large stones of any kind at all) based on appearance of mortar/concrete in photo (looks like it was poured into form mold made of planks, so thinking it's early post-war concrete construction).
A hammer drill with the right bit will drill a hole in solid granite suitable for a typical small expansion bolt quite quickly. Rock climbers do this all the time.

what kind of hammer drill and drill bit are you using to go through the reinforcing steel ? 10-15+ mm reinforcing bars are pretty common here and hitting one means a lot of swearing and choosing a different place for the hole

Nope, no reinforcing steel here, when i have time i'll go find my hammer drill and put holes in that wall.

Hey X, must be nice having one of those. Many years ago as a teenager into CB radio, my parents let me have a station at home. The radio was in the finished basement of an almost 100 year old house with a fairly thick stone foundation and to get the coax inside, my dearly departed father handed me a hammer and a cold chisel and said have at it. Since the tip of the chisel was a cross point, he said to make sure I rotated it every couple of strikes. What I would have given to have a Bosch like that.
I have used a star chisel and 4lb hammer to drill a hole. not recommended. The Bosch SDS with the Bosch bits will go through reinforcing with a little extra delay, I was using a very large one ( rental tool, I do not have a SDS drill that would do a 75mm hole through 400mm of concrete) and after about a half hour I heard a different note, and after the large plug fell out I found I had cut through a piece of 25mm rebar making the hole.
Not as bad as when I called "rent a hole" to do some 110mm holes for new drains, they broke 2 thin wall diamond cutters making the one hole. When I was getting a drain made Ivan the plumber dropped off Bongani, with a chisel and a 4lb hammer, and made an outline where he wanted the drain cover plate, and went off to the next job. I called Ivan about a half hour later and Bongani said " Hau Baas, faga lo jackhammer manje" ( boss, bring the big jackhammer now). He took 2 days with that to make the hole, as the concrete floor there was also cast 400mm thick over the sand, with reinforcing, mesh and sheet steel shuttering under it still. When we dug down to the sewer line we found out we didn't really need those 200 bricks either for the manhole, as we got over 400 used bricks out of the hole, along with the sand for the cement. When we were at the sewer level we also got sea water as the tide came in.
Have you thought about hanging the shelves from the rafters? That's what I plan to do in my basement lab. I had enough fun drilling the relatively small holes in the concrete for the electrical conduit anchors.
Yea, I'm using 12V and I did go up to 13.8, and as expected they get hotter and brighter at 13.8. 12V is plenty bright for my use.
How much current do they draw?

Two of them were running at a little over 1 amp.
I'm about to finish off a small bench for small scale projects and research. There isn't much room for more equipment on the bench itself, but it's enough for its purpose. I might build a small platform if need be. There's more equipment on the other side of the shot (drill press and other stuff). I took Dave's advice from his diy acoustic panels video and built a few to ease off the reflections. Most of them went to another area where sound recording is relevant, but a few of these panels stayed in the bench area to good effect. Well, that's about it. Oh, notice the book. It's a beast! I just got it today in my mail and I couldn't be happier!

What a transformation! Looks like a good use of space. May be hard to work and read your bible there at the same time htough considering it takes up 50% of your usable space
. Loving the fact that it's next to a window though. Must be nice to work on projects during a nice day outside
