The card carries these facts from its Wikipedia article.
- An electric current in the gas excites mercury vapor, to produce ultraviolet and make a phosphor coating in the lamp glow.
- Fluorescent lamps convert electrical energy into visible light much more efficiently than incandescent lamps, but are less efficient than most LED lamps.
- The typical luminous efficacy of fluorescent lamps is 50–100 lumens per watt, several times the efficacy of general lighting incandescent bulbs with comparable light output, which is on the close order of 16 lm/W.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Fluorescent lamp article was read about 120,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 85 and blocks with 74: each hit it takes is cut by 30 %.
