T10 21-LED White Light Car Angel Eye (70mm Diameter)

Pros: Very bright and homogeneous light. Not blue or yellow either, somewhere in between.
I used this to build my own ring light for my SLR:

Cons: Not really, it does what it is supposed to.

Other: Good product, versatile use. The ring gives and even distributed light, I am thinking about using it for interior lightning as well. As far as I can tell these LEDs does not require complicated electronics just an adapter which gives 12 V DC. I am using mine from an old laptop power supply with a single chip 12 V voltage regulator. The simplest regulator is OK for 1 A which should drive 4 rings easily.

Pros: -The price is just stunning. You get 21 PCC2 chip leds and a PCB. In regular online stored, only these LEDs are around 80 cents each, so even if you would only need the LEDs for DIY projects this item is vey good value.
-Nice color, almost between 6500K and 3500K, so not too warm and not too cold.

Cons: If you want to use them as where they are intended for (automotive), re-solder the wires and use some kind of epoxy to prevent the solder joints to stay well under vibration conditions.

Other: Value for money!!

Pros: Optimal pure white light source
Great visual effect in the headlight
Ótima fonte de luz branco puro.
Ótimo efeito visual no farol.

Cons: 1 to easy to use rate because for automotive use you have to open your headlight and this is definitely not an easy job.
Wiring too weak, I had to solder a 20 AWG wires.
1 para a nota de fácil de utilizar porque para o uso automotivo você tem que abrir o farol e isso definitivamente não é um trabalho fácil.
Fiação é muito fraca, tive que soldar fios de 0,5 mm.

Other: Could be supplied painted in black or chrome to match the headlight.
Cheaper by the unique look!
Poderia ser fornecido pintado em preto ou cromado para combinar com o farol.
Barato pelo visual exclusivo!

Pros: LED's are very good, high quality, good bright light. easy to see as daylight in the city. The price is also realy fear. Despite of the (just) 70mm there are a lot of LED's attached

Cons: The wire's are very weak and break very fast from the angel eye. also at the end of the line, there is a socket witch is realy weak. it is made out of plastic witch breaks very easy.

Other: for the price it's a realy good product, but I still advice to change the wires. I will advice you to buy this product, I'm realy pleased with it.

Pros: Nice, bright, cool white LED's. I have used it for Englel Eyes, on Fiat Punto mk2a. Main light projector has a diameter of 70mm, and fog light projector has a diameter of 60mm.

Cons: Compared with 60mm LED ring, there is a different colour temperature. Not big deal, anyway it looks nice. Power supply cable (with T10 socket) could be a bit longer, so i had to extend it.

Other: It looks really nice in combination with Xenon headlights 4300K.
