| 01:38.25 | solar | ds2: forgot to get those 1W LED's today. Don't expect I'll be back down in that area till monday.. So no feedback today. |
| 01:38.52 | ds2 | solar: I read that carefully and the description is misleading |
| 01:39.02 | solar | oh yeah? |
| 01:39.07 | ds2 | up to 1W of power consumption....not that it has a 1W LED :( |
| 01:39.18 | solar | bah |
| 01:39.19 | solar | thanks |
| 01:39.31 | ds2 | so I am guessing it is probally a 0.750W resistor and 0.250 of LED :( |
| 01:40.07 | solar | then the next best prices is around 7 bucks for a single ;/ |
| 01:40.13 | ds2 | so that means the maglight retrofit bulbs aren't too bad |
| 01:40.23 | ds2 | but they are $20 a pop |
| 01:41.26 | ohsix | i've found em on sale often enough to fill all mine out :] |
| 01:41.43 | ds2 | who ever has maglight retrofits on sale? |
| 01:41.53 | ohsix | i bought one at regular price for a 4 cell, its worth it, its not so great when you need to get the flashlight and the thing at the same time |
| 01:42.02 | ohsix | harbor freight, sometimes home depot, lowes |
| 01:42.15 | ds2 | they are clones, right? |
| 01:42.39 | ds2 | the clones tend to not have removeable bulbs |
| 01:42.48 | ohsix | nope, from mag |
| 01:42.59 | ds2 | hmmm |

| 01:49.12 | solar | color = amber; Ok. |
| 01:50.20 | solar | yeah 7-9 still. oh well |
| 01:53.16 | ds2 | that is a 1W LED |
| 01:53.40 | ds2 | but that is a bare LED, you will need heat sinking |
| 01:54.38 | ds2 | here's something similar mounted on an aluminum disk for heat sinking: |

| 01:56.38 | solar | yeah those were about the same as I was seeing last night but can't find tonite for about ~7 |
| 01:56.43 | ohsix | what are you looking at leds for? |
| 01:57.09 | solar | it's the embedded things to do :) |

| 01:57.32 | ohsix | ic, http://www.luminus.com/content1044 |
| 01:57.48 | ds2 | DX has some of those cheap, IIRC |
| 01:58.04 | ds2 | ohsix: we are both interested in very low power lighting |
| 01:58.09 | ohsix | i like the form factor |
| 01:59.28 | ohsix | pretty much anything you're looking at is going to need special mounting |
| 01:59.54 | ds2 | the mag light retrofit bulbs come close to not needing it |
| 02:00.15 | ohsix | ya but the mag has a direct connection to the housing assembly too |
| 02:01.04 | ds2 | it is not completely clear if that assembly itself is sufficient heat sinking by itself |
| 02:01.22 | ohsix | i have a few of these, they light up a large room by themselves http://www.cree.com/products/xlamp4550.asp |
| 02:01.33 | solar | is guessing 4-6 would make nice track lighting above the window |
| 02:02.29 | ds2 | if you got the budget - |
| 02:02.31 | ds2 | http://www.amazon.com/Diamond-LED-flashlight-replacement-flashlights/dp/B000CQ37RA |
| 02:03.51 | solar | You Save: $85.05 (77%) <-- that seem anywhere neat right? |
| 02:04.04 | ds2 | hahahhahahah |
| 02:04.32 | ohsix | the light assembly in a maglight is gr8 at getting heat away from the device |
| 02:05.06 | ohsix | still, the led retrofit is much much cooler than the xenon bulbs |
| 02:05.15 | ds2 | worse case, a hour or two on a lathe should get you something equally effective |

| 02:45.39 | solar | what would you do with such bright sources? |
| 02:51.48 | MonMotha | solar: if you can come up with a decent diffuser, they're usable as general room lighting |
| 02:51.55 | MonMotha | they can also be useful as task lighting as they are easily dimmed |
