Article summary

The author, who recently moved to Boston, found it difficult to focus after dark due to the early sunset. To combat this, they purchased an extremely bright LED bulb, which emits as much light as 40 incandescents, and placed it next to their desk. The bulb significantly improved their productivity and made their living room feel cheery. The author notes that the cost of running the bulb is relatively low, comparable to a modern fridge or a load of laundry.
