I might buy this...but there again, is that a 'lace-webbed spider' reference? ha ha ha...

 

 

wait a minute...why 835K white?...that looks far too 'hot'....my last bathroom bulb was a 3500K:

oh I see...a 'confusion' of entries...the following looks like more like the one that I want although it's still 835k - why?

 

16w 3500k 4pin...go figure:
