## Description

Product Description Sylvania 20668 DULUX 18W double compact fluorescent lamp with 4-pin base, integral EOL, 4100K color temperature, 82 CRI, for use with electronic and dimming ballasts, ECOLOGIC From the Manufacturer Upgrade to the 18W 4-pin compact fluorescent bulb that offers dimmability, long life, and serious energy savings in a compact double-tube form factor. Designed exclusively for electronic and dimming ballast operation, this plug-in G24q-2 base lamp installs easily - just drop it in and dim it down. Delivering 1,150 initial lumens at 82 CRI, rare earth phosphors ensure cool white 4100K light that renders colors accurately and naturally. Whether illuminating a retail showcase, a recessed ceiling fixture, or a garden walkway, the double-tube design provides efficient photometric performance in a smaller overall footprint than single-tube alternatives. The 20,000-hour average rated life is where this cfl light bulb truly stands apart - lasting up to 20 times longer than a standard incandescent and twice as long as many conventional CFL bulbs. Mean lumen output holds at 86% throughout the lamp's life, so light output remains strong and consistent from first use to final hour. Fewer replacements means lower maintenance costs and less disruption to your space. Energy efficiency is built in at every level: this 18W lamp uses approximately one quarter of the energy of a comparable incandescent. When paired with an electronic dimming ballast, the system maximizes savings further - reducing wattage and electricity costs whenever full output isn't required. TCLP and RoHS compliant, meeting Federal non-hazardous waste criteria in most states. Available in 13W, 18W, and 26W across 2700K, 3000K, 3500K, and 4100K. A trusted 4-pin cfl compact fluorescent bulb for contractors, facility managers, and homeowners who want controllable, long-lasting light.

Review: This is a lightbulb. - This is a lightbulb that fits in a somewhat oddly shaped socket. In my case, a bathroom light/vent combination. It is really quite wonderful. Thanks to a handy switch that is installed on my wall, I can turn it on freely on a whim. I find this most useful at night, as the room becomes very dark at those times (although recently the moon was full and the skies were clear, which made the light bulb superfluous). Perhaps my favorite feature is the ability to turn it off - this results in amazing energy savings when I am not in the room, or even during daylight hours when there is enough ambient light to see. Overall, I give this light bulb a five star rating as it has illuminated my bathroom to my satisfaction every time I have needed it (and even one time when I did not but flipped the switch out of habit)! I gave it merely average scores for "value" and "longevity" as I do not feel the few weeks I have had it installed long enough to really judge it for such qualities.
Review: I purchased the 4100K 18W bulb. These replaced the ... - I purchased the 4100K 18W bulb. These replaced the stock lights in a Panasonic Whisperwarm bathroom fan. The stock lights lasted about 2 1/2 years and were not very bright, more of a yellow light. These are a bright white light, which I prefer. These are a noticeable improvement, but time will tell how long it will last. For the price, it's worth the purchase

### ⭐⭐⭐⭐⭐ Great Product for the fraction of the cost
*by L***S on September 3, 2011*

My bathroom fan's light bulb had gone out. The cheapest original replacement bulb that I could find was over $20. So I ended up purchasing this item. With slight shaving of some of the plastic on the base of the bulb, the light perfectly fit in to the fan and it works perfectly... This was a great deal.
