This one is a plant that prefers low light situations, so reasonable indirect daylight is good. It won't have done it any favours leaving it near your grow light, but I'd be surprised if the brown tips occurred so rapidly as a result, so I'm assuming they'd started before you moved the plant.
Keep it away from any heat source (your grow light may also be producing heat) such as radiators, water when the surface of the compost feels a little dry to the touch, and when you water, do it thoroughly, tipping away any excess left in any outer pot after thirty minutes. Brown, crispy tips are usually caused by dry air and dry at the roots - soft, soggy brown tips is usually overwatering and/or leaving the plant standing in water.
Note; I watered mine with London tapwater for the 8 years I had it, without a problem, but you can switch to deionized if you like. You can trim any dry, brown tips with a sharp pair of scissors if you don't like the look of them, but wait till they dry out if they're a bit soggy.
As for whether its dying, I think I see the tip of a perfectly healthy leaf in the centre, and the appearance of the plant overall does not suggest its about to expire.
