The Torchstar from Amazon is the first LED bulb I've seen that looks like it could work OK.
One general problem with Leds is that the light emits from a point outside the center of the reflector. A halogen filament is at the exact center of the reflector, which is what the reflector is designed for, and that gives a good light distribution. With Leds, the emitters are always somewhat offcenter, which then throws the light in a bit different direction from the reflector. Even a small distance from the center makes a huge difference in the angle of the reflected light. This particular bulb is very thin, and the emitters are closer to the center than on most other Led bulbs. Looks promising.
The four feedbacks in Amazon on this bulb do not mention light distribution as an issue, so that's good.
The description mentions that if the bulb gets too hot, the light output is reduced. How will this work in practical terms? Will the light be on the low setting half the time if they are on continously? Or only on hot days? One drawback on the 100 (and on most cars nowadays) is that the low beam is on even when the high beam is on, which makes the lows run hotter, and last shorter.
Then it's the issue of radio noise, which is a general problem with Led drivers (integrated in the bulb), and with USB/cellphone chargers as well. This is mentioned by one of the reviewers on Amazon. The original radio in my 100s is particularly sensitive to interference, and any cheap Led or USB charger interferes with radio reception on FM. Even the Garmin GPS, which supposedly is of high quality, interferes slightly on weak stations. So what will this relatively high power Led bulb do?
The color temperature of 6000 K is slightly whiter than most halogen bulbs, so it will look different from original.
There is also the issue of lamp housing temperature. With halogen, the housing and glass (lens) is kept at a relatively high temperature, wich reduces problems with humidity inside the housing, and keeps the glass free from snow. With a LED bulb, the power is lower, and most of it is emitted at the back, outside the lamp housing, where the cooling fins are. What will this do during snowy winters?
Awaiting more feedback
