We've had two go out in our first 45 days. We found replacements at WalMart in both 10 and 20 Watts...recommend the 10Watt. 20 Watt seems to burn awfully hot for the confined space of the plastic cover.
Also, make sure you don't buy the kind that have glass between the two prongs. They don't work.
Unfortunately, these bulbs are $4+ apiece at Walmart. Ridiculous, particularly if they are a high use bulb. And if someone has an alternative, pls let know the specifics.
