back from another reloading bench thread, I got a few PM's on LED lighting I used on mine. Totally forgot about it for a bit - so here they are.

I had an issue awhile back with the halogen lights I was using and the heat they generated. I was surprised at how hot the wood got with them. to the point where it was actually cooking the resin in the wood. Got me to thinking that's not such a good idea... so I went in search of LED's.

What I discovered there was there are about as many LED makers as there are cars. And about the same variation in quality. After being disappointed with several sets I found one that I like. Most of the ones I found were cheap chips, and often poor backing and they'd heat up and fail quick.

Ended up buying from a company called FlexFire. They have a lot of internet hype - but nothing much concrete I could find. They're a California company, but that's about all I could really dig up. Well, after talking with the (English speaking) person on the phone for a bit, I got the impression that they actually knew something about them, and not just sales hype and hyperbola. so I ordered a bunch for the bench, and my kitchen.

The upside - the chips are decent quality, and are soldiered to the strips well. They also back up their light claims. When I powered them on, I was impressed to say the least. The ones I am using in my bench are the ultrabright "design series" in their "bright white" color temp. which are the "dimmest" in that line. and I'm actually glad I didn't go brighter.

The downside - they aren't the cheapest ones out there. With the connectors and power supply - that 4 foot strip was $75. Conversely - the "color bright" units I bought for the kitchen were $175 for 16 feet and the power supplies.

Here's a few shots of my bench with ambient light, the old halogen lights, and the led's. I'm still working on hiding the wiring for the LED stuff though. for now good old 3M double sided tape is holding them in place. One additional thing - they recommend mounting to some sort of heat sink for the really bright ones, and the higher voltage ones, so I mounted them to a cheap aluminum bar from home depot. I will probably recess them and make them a bit nicer install some day - but it's a work bench, and they're really not visible anyway - and the rough look seems to fit somehow.

The lights are not off in the room. all the other lights are still on, the ambient light is actually pretty bright, I changed out the light bulbs from the first picture so the room is actually brighter than it used to be when the first picture was taken. these things are bright enough where the camera seriously adjusts the shutter to compensate.

The pictures kinda crappy, but this is how bright it is if you try to adjust for the same ambient light level as it is with them off.

I use a two-lamp, four foot flourescent shop light with two Cool White lamps. $9.99 at Wally's.
 
If anyone wants to play around with some really bright LEDs, these are quite nice at a reasonable price. The viewing angle is only 15*, so they are best for spot applications, and will require a current limiting circuit. I use one to light up the powder charge on my 550b with a couple mirrors to see into the case. I use a 5V regulated supply (a little switcher wall wart cannibalized from a failed piece of electronic junk), and a 51 ohm resistor - no reason to get any more complicated with a single LED application.

5mm discretes don't require any special cooling, unless they are packed into a high density array. Ask me how I know... Or rather, ask my boss from 20 yrs ago why I had to prove to him that dissipating 20W from a 2"x2" array inside a small box was a bad idea. Total thermal meltdown in the center. Fortunately, it didn't catch on fire, so I lost that part of the bet.

anothernewb - like that setup. Nice layout.
 
There are a lot of really good LED products coming to market.
You can now get 4 ft tubes to replace fluorescent bulbs, including T8 style bulbs that can be used in T8 or the standard size fixtures., price is not cheap, but light is excellent and will last 50K hours.

I have replaced the shop lights in my laundry room and above my loading bench with 4 ft LED's. They were approximately $40 each with tax. A little expensive, but the lighting is comparable to what Anothernewb shows in his pics. Have attached 5 ft plug, so requires outlet in ceiling or close wall.
Tried to find on Lowes web site, but they do not list it. It is a Utilitech product, which is Lowe's house brand. They do show a double light direct mount, but it is $68 plus tax.

As I can justify it, I am replacing all lights in my house with LED. It will take several years, or a serious reduction in LED prices.

+1 on Cree, they are, i believe, the world leader in LED light development. Except for the shop lights, all the LED lights I have added to my home are Cree.
I refuse to by GE if I can help it.
Warning off topic: GE made a profit of approx $11,000,000,000 ($11 billion) in 2013 and paid exactly $0 on taxes. They were also behind the banning of incandescent light bulbs.

I don't have a pic and am at work but I bought a strand of LEDs from superbrightleds.com They can be cut into 3 led sections and used with any 12v dc adapter. I mounted 3 on the press itself so they shine right down into the cases. It works very well and cost like $10.

I get these through Amazon for my boat, night fishing. There are 2 different led's out there with the 5050's being the brighter ones and 3528's. You can also get them so they are water resistance, for my use. They come in 5 meter lengths. Just for your info on how bright they are. I have 4 meters (green) around a 1" pvc pipe 2' long sealed inside a 2" clear pvc. I can submerge the light down to 23' of water and still see the glow on the surface. I have 2 3' lengths of the white ones on the inside of my boat. With these on it's like being in the sun, they will blind you. I also have the UV wavelength to make my fishing line glow so it's easier to see.

These can be purchased with a kit if you need controls. The ones I get are a specific color, wht, grn, UV. You can get the RGB that can do all colors, then you can set the color to what you want with the controller. The dimmers use a PWM controller.

These are a very good option for cheap lighting.
