There may have been a marriage or such a quality of the lamp; if this is the case, then the price does not correlate to the lamp's quality. I purchased this lamp for a space that was not very large; but, for a space that was somewhat larger, I purchased a 550S model with a metal edge. This model does not have the drawbacks that were discussed earlier. The temperature in the first two photographs is 450C.
