Review on High-Performance Pack 13 Watt Double Tube: Efficient Lighting Solution by Stephanie Hughes

I finally found a lightbulb to hold on to. I've tried branded CFLs (GE, Phillips) and even LED bulbs. There aren't many options for a 4-pin configuration. My favorite color is 2700K warm white. This is the cheapest lamp I can find in this color. Even the most expensive lightbulb, which costs 3-4 times as much, does not even last half the advertised lifespan. I have 20 lightbulbs in my house and every year I have to change 3-4 on average. The lifespan of this lamp is about the same as a more expensive lamp, but costs 1/4 the price. Flicker-free, instant on, colorfast (for warm white) and cheap. What do you not like yet?
