The Best CFL bulbs I have found
By Robert Stoll
Trying to “go green” has been an pricey proposition since so a good deal of CFL bulbs out there are plainly terrible. They either take too long to light up or the light color isn’t what is advertised on the box.
I’ve tried at least a dozen dissimilar brands and the ones that stand out the most are these “instant-on” CFL bulbs from Sylvania. While they assert to be “instant-on” the reality is they are in all likelihood at 70% light when you primary flip on the switch but get to full light within 15 seconds. I don’t find this to be a shortfall of these bulbs as all CFL bulbs suffer from this, and you do get applied to it after awhile. Other bulbs take even longer to get to full light.
What I like most when it comes to these bulbs is that the color is genuinely Soft White. Way too some bulbs out there assert to be Soft White with a Kelvin rating of 2700K but for the vast majority of bulbs I have tried the color was way too white – like a regular fluorescent bulb. Not these. These have outstanding color that looks just like your regular incandescent bulb when wholly lit.
I’ve put 65-watt equivalent Sylvania bulbs in some of my light fixtures (i.e. in ceiling fans) but if you want to replace canned lights in the ceiling I would in all probability commend getting these 75-watt equivalent bulbs. They put out with regards to the same light as a 65-watt incandescent. Unfortunately, these bulbs are ‘spiral’ so not as finelooking as an indoor flood but for galore reason these bulb makers can’t seem to take good spiral bulbs and put them in an indoor flood format.
While CFL bulbs have their shortcomings over incandescent, I may attest that in the original two months that I’ve had these installed all around my house our kilowatt hour usage has been 50% LOWER than in comparable months in years’ past. There are evidently a lot of components that go into this but I would say we are saving at least 1/3 – 1/2 on our energy costs, so the investment in these bulbs is well worth it.
One final note: these bulbs are NOT dimmable. I reviewed another CFL bulb that is dimmable and good if you check my prior reviews.

Great energy effective substitute to incandescent bulbs!
By P. McCarthy
Sylvania produced the Compact Fluorescent Light (CFL) and they seem to proceed to be the leader in the field.
PROS:
1: Instant-On. As soon as you hit the switch, they light up. Some CFLs take up to a second to turn on after you hit the switch. This causes people to flick the switch on and off a good deal of times because not one thing happens instantly. Can be confusing.
2: Good firstborn luminance from cold-start. One downside to all CFLs is that when you turn them on after being off for over 20 minutes (cold-start), they take time to warm up and obtain full brightness. On cold-start, these Sylvania CFLs are when it comes to 70% of their eventual full brightness. Sylvania 29781 CF13EL/MINI CFL 3,500K are full luminance from cold-start, but the color of the light is closer to halogen than incandescent (they’re a lower wattage but I mention them for comparison). Other CFLs I’ve tried were so dim on cold-start (imagine a cigarette lighter) that I had to wait a couple minutes for them to reach full brightness: Frustrating, potentially dangerous and just plain unacceptable.
3: After cold-start, quicker to full luminance than most CFLs. Similar to my last point, it doesn’t take the CFL very long to reach full luminance after cold-start. As mentioned, the only CFL I’ve ever seen that has full luminance at startup is Sylvania 29781 CF13EL/MINI CFL 3,500K.
4: Warm light color. The light color from these CFLs looks very close to the yellowish-colored light from incandescent bulbs. These are NOT the blueish CFLs that look like hospital lighting!
5: Tiny little bulb!
CONS:
1: I wish they were full luminance at cold-start. Better than most, but since Sylvania has demonstrated their capacity to develop Instant-On with Instant-Brightness, I would have hoped their most recent CFLs would have this function.

Blew out in 6 months
By Frank Frank
Even after minimal use, it blew out after 6 months. So I do not commend this brand.
