I would definitely recommend you do your research. I recommend the circuit on board which has LEDS facing down only.
Nearly all the ones on eBay and amazon are the 100 lumen variety from China. I bought 20 of them but find them them dim compared to regular bulbs. I finally found 350 Lumen ones on dhgate (a Chinese ebay). Here is the item:

It is available in Warm white and cool white but be aware that the warmer the LED the less usefull light it puts out.
I haven't yet received them but will be sure to do a review of the seller and bulbs when they arrive.
