T10 Wedge 2323 High Power Chips 1W White/Warm White LED Light Bulbs W5w 194 168 192 921 20-pack (20 x T10-1W) (Warm White (3500K~4000k))

If these were built a little bit better I would have not known how crappy these are.The first one fell apart when I removed it from the socket, then the next, then the next.Each one of these are loose. After further inspection, the lens and aluminum trim (not heatsink) are snapped in. The LED is tucked in and held to the socket with only the leads of 2 resistors.Resistors do not regulate voltage, they are current limiting. Not a really safe way to wire LEDs. Especially in something expensive like your car. Back to the aluminum trim. In this design the aluminum sits on top of the LED but since its loose it does not provide good heat dissipation.I can't prove it but I swear that the description said that these are Samsung 2323 SMD. These are not Samsung.Returning these.

I used these to convert over from incandescent bulbs that were costly to use and replace to these. I was using 14 watt incandescent lamps prior. So with these LED lamps which draw 1 watt, 14 fixtures draws what 1 used to. MUST USE DC POWER SUPPLY! Home Depot and Lowes sells AC output transformers which will burn these up. You can add a AC to DC rectifier which are cheap to make your AC power supplies output DC without replacing them or use a universal switching power supply. 30 amp which averages $17 to $20 here on Amazon. These also have a heat sink which makes me more confident they will last versus most others where the LED is on cardboard. I would recommend and will be buying them again for sure. Used them in the walk lights in background. Yes I love landscape lights lol

After about a year, they started flickering. My daughter thought the car was a dance party. I really liked the color, they matched the regular bulb really well, but unfortunately, they did not stand the test of time - not just one, I have 10 in the van and 8 of the 10 started to flicker. Upon removing them to change them with a different brand, the housing came apart and the wire leads got stuck in the socket. Most of them had to be removed in 3 pieces with needle-nose pliers. I really loved the color, though.

Were bright enough but they are a bit too long for some of the fixtures.

Not have long live time

good
