Those are not meant to be used as primary sources of illumination. They give off 250, maybe 300 lumens. Thats about the same as your turn signals or a handheld flashlight. Most people buy those "bulbs" for fog lamps for purely aesthetic purposes. As far as using them to see anything, you'd be better off getting a candle.
Far from it. There are only a few LED modules out there powerful enough to compete with halogens/HIDs in the thousands of lumens range. I belive the new Audi A8 uses LED headlights, the new Mitsubishi Leaf, Cadillac Escalade, and the Lexus Ls600 series. Not only do they emit INTENSE amounts of heat (the whole housing is a heatsink) they use a combination of reflectors and projectors to get proper beam control, because they are using one MASSIVE LED die instead of many small ones. I believe that single die is rated at maybe 27W. Retrofitting LEDs is a LONG ways away. I'd give it maybe another 6-7 years before they are common place and manufacturers can get the heat down and output up.

LED sealed beam replacements.......
I do agree with you that they do produce alot of unwanted heat.....jw speaker #8700 has a ungodly sized heat sink on the back if it....

Never changed a headlight since around the mid-70's.
I just imagine that they change out lots easier than back n da day.
Trim ring had to be removed, and if a spring was attached for aiming onto the trim ring, LOOK OUT!!
Usually 3 slotted head sheet metal screws were used to hold the trim ring, and they stripped constantly.
When installing the new sealed beam, the spring had to be re-stretched back to the trim ring and that's when things usually started going wrong.

Lasers WILL be the light source of the future.
Along with many, many more applications.
I recall reading my 'Weekly Reader' back in the early 60's about the developement of Lasers (Light that has been Amplified by Stimulated Emission of Radiation)

Raptor,
I think you'll find that the older A-Pillar mounted spot lights used by many police agencies had a sealed beam similar to the aircraft landing lights mentioned. They are indeed pretty bright. The amperage draw was pretty significant if I recall correctly.
I used to have one in the basement. Let me see if I still have it.

There are already LED and HID swap out units on the aviation market. Of course its a simple AMP-style 35W ballast with a tiny light, for $700!

I have been running Philips X-Treme bulbs for 2 years now with no issues what so ever. The benefits are miles over stock. They include shining more light to the curb side of the road, brighter beam further down the road without causing glare onto on comming traffic. There are sharp cut-offs on both beams. I find these to be great when traveling at night on unlit roads and highways making the drive less stressful as the light does travel further down the road. As their site states it's where the hot spot is in relation to the reflector. These seem to cast light where it's needed. I also have a set on my Boxster as well. They do last a long time.

if the link worked, I'm pretty sure I need the H13 for my headlights and i've read here that i can run the 9005's in my fogs (square housings).....but on the amazon site where you choose what type of vehicle you have, it says that niether one are compatible with my truck...i can understand it saying that for the 9005 since that's not the OEM # but dont understand why it says that for the H13....Just looking to get a final Go/NoGo on these bulbs before I order.......2004 lariat, square fog housings...TIA
