Amazing lights - incredibly bright, very pure light. Amazing wide beam, great throw for LED light too. I should say that they are not 3000kelvin, the tungsten 35W 3200kelvin bulbs I was replacing were slightly warmer in colour temp and significantly duller in output and significantly hotter to touch. For under a 10th the power consumption you get more light, a more clinical light but great for what I wanted them for. Worth noting I only installed them this morning, so I can't comment on durability. A few months on and 49 of the 50 are working well, one now only outputs about 10% of the original lumen output.
