'Sun Burn' In SingPost HQ

I'm wondering why Singapore Post Limited (HQ) or Singapore Post Centre at Eunos Road is using these extremely bright and hot spotlights at the lobby (ground floor). These spotlights (some pair, some in 4s) are shinning on people who are queuing up.

If you are under these spotlights, it takes less than 1 minute and you will be perspiring. Try it if you don't believe. Aesthetic aside please, probably energy saving white lights (cooler) are much better for everyone. If the lights are making people perspiring and uncomfortable, why the need for aesthetic appeal?
