40 W type, power consumption 8 W commonly used. Lifetime, energy saving performance, brightness, price, both were satisfactory products, but currently not being manufactured, looking for alternative items. However, manufacturers handling bulb-type fluorescent lamps of 40 W type are getting less, and even remember irritation at each company's product lineup. From the viewpoint of energy saving, there is no choice of 60 W type, but I am not interested in developing LEDs. Demand for the 40 W type should be reasonable, so development of alternative products is desired.
