I think the first one uses Tungsten bulb which provide yellowish lights. See thread below: http://hipgirlclips.com/forums/showthread.php?t=215
The 2nd one is the normal tabel lamp. Just need to purchase a true white bulb. Here is one from amazon.com 2pack: http://amazon.com/o/ASIN/B000K1MIZO/...pf_rd_i=507846
Just search amazon.com or eBay for '5500K bulb', or '5000k bulb', '5300k bulb', '5600K bulb' and you'll find some.
