Lupus patients are EXTREMELY sensitive to sunlight (ultra violet) and fluorescent lighting. We are told to protect ourselves from fluorescent light when we are in department stores, our offices or anywhere else that might have fluorescent lighting.
If possible, advise your job of your diagnosis and your "allergy" to fluorescent lighting. Ask if your office can be fitted with incandescent lighting (which, by the way, is supposed to be phased out. However, the LFA is fighting this because fluorescent lighting can cause life threatening flare ups in Lupus patients).
In the meantime, make sure that you ALWAYS use sunscreen (minimum SPF of 35), wear protective clothing, hats and sunglasses (yes, even indoors if you have to). Exposure to sunlight and fluorescent lighting is very detrimental to our well being and that is what you are feeling...symptoms of a flare up that can be very serious.
I hope that I've answered your question. Please do take special care to avoid sunlight and fluorescent lighting!
Peace and Blessings
