Well, I felt that same way and bought those LED lamp units for pot lights at HD and one of them failed within a few months. It may have been an anomily or a bad omen, but either way, with 70 bucks for 2 bulbs, I returned both of them for refund.
Other than the failure, I was VERY pleased with their dimmability and color and brightness. I have the Lutron dimmer for CFLs and LED lamps installed. I went back to 2 R30 incandescant bulbs for now.
Sometimes being an early adopter leads to dissapointment. I hope most other users have better success with them. I bought a few LED lamp bulbs that I use in table lamps, but they are built oddly in that they are directional and do not emit light any where as evenly as an incandescent 40 watt bulb that these replaced.
Last week I bought some other design bulbs at Costco that have 17 LED's in them that are more omni directional, but emit much less brightness than the other ones. I do not remember the stated Lumen output of these 2 types, but I thought they were identical. It appears to be like a 40 watt bulb vs a 25 watter. I put one of each type in the lamp on my night stand, and the difference is so obvious. Going to measure the actual wattage of these 2 types with my Kill A Watt device for comparison. It seems to be able to measure down to 10th's of a watt if I remember correctly.
