Question: Streamlight stylus pro c4 (48 lumens) Is this being sold on Amazon.com as yet? The new stylus pro C4 part numbers appear to be the same as the older stylus pro.
Document: It's a good light. I have noticed that the new C4 versions have had more problems with cross-threading, but Streamlight has excellent Customer Service if you should have that problem. I think the Stylus Pro would make an excellent EDC light, or part of a kit.
The Stylus Pro uses a Cree XP-C emitter, but Streamlight calls it their "C4" LED. This emitter, coupled with the smooth reflector, give the Stylus Pro a nice, tight hot spot. It also introduces some visible rings, but they're negligible in real-world use. Output is double the old version of the Stylus Pro - 48 lumens. The lens is clear polycarbonate (plastic) and does its job.
I just baught Streamlight Stylus Pro 66118 Black. It uses 2 AAA batteries. It Produces 48 Lumens (Not 24 Lumens as shown in the ad description)It uses C4 LED. Runtime is 6 Hours. Comes with 2AAA batteries,a spare tailcap boot and a belt holster.It is 200 percent Brighter than naan C4 LED flashlight.I am very satisfied with this flashlight.Again out-put of Streamlight Stylus Pro 66118 Black is 48 LUMENS. (Not 24 or 20 Lumens as shown in the ad description.
This is an awesome little light in a compact package. I carry it daily clipped inside my pocket like a pocket knife. The battery life is acceptable for the brightness, and at 24 lumens it is surprisingly bright focused into a tight beam. Streamlight is coming out with a revised model in May/June '11 with a C4 LED, putting out 48 lumens with a 6.5 hour runtime. I will probably give this light to my wife and purchase the new model.
I was a bit hesitant to buy the Streamlight Stylus Pro as there was some bad reviews. I must say I am very impressed with this flashlight right out of the package. It is very light and very bright. 48 Lumens out of this little guy!!!! The pocket clip is firm but not overly tight to clip onto your pocket or pull out of your pocket but it will hold it in place perfectly.
Received  the 48 lumen C4 led stylus pro pen light. Nice clean beam with good spill, batteries came included. I wouldn't replace alkalines with rechargeable. Per streamlight's web page this light is alkalines only. FYI I have killed a couple of lights when using rechargeables on alkaline only lights. This light fits easily in my pants front pocket, clip is strong enough to hold it in place without worrying about losing it.
and if a Sure Fire isn't handy it's still my next choice. At around 20 bucks, available in three or four different colors, and using just 2XAAA batteries, The Stylus Pro is the perfect compromise between high quality, high performance, size and overall economy. It's also very strong and durable.Prior to finding this light for a STEAL on Amazon.com, I had a buddy's on extended loan.
According to the specifications shown on back of package card, the 66118 Stylus Pro LED I received actually produces 65 lumens and not 48 but anyhow, the price was very competitive for a flashlight of this size and brightness.
First off I purchased this penlight for my First Aid Kit as a dedicated light, just in case it was needed in an emergency situation. At 48 lumens and ~6 hours of battery life this met my needs in my usage perfectly, but is not sufficient for my other flashlight needs.The Stylus Pro feels good in the hand, well balanced, thin and the top button is stiff enough you will not accidentally turn on the light in your pocket/bag/glove box.
I recently bought the streamlight 66118 stylus from Amazon.com, as an addition to my Every Day Carry items. I was unhappy with the short fat flashlight hooked to the outside of my belt, and wanted something slim, that I could carry in my pocket. This one really fits the philosophy of every day carry. Compact,well made, light weight and very powerful. This light will ride in my pocket for years to come.
