This review is from: 110V 15W LED Corn Light Bulb (100 watt Equivalent) 1600 Lumens - E26 White
Pros: Very bright, low power consumption, high service life expectancy
Cons: High, harsh color temperature. Can not be used without a shade as a bare bulb. Longer structural size than normal.
Other Thoughts: Some may find a high color temperature uncomfortable (typical 'warm' light is around 2700K, this light approaches 6000k), but I'm an advocate; just a personal preference. You can not use this light without a shade/diffuser as it is harsh...think LED flashlight in your eyes harsh. It is longer than a typical bulb; price for multiple sets of LED outputs. Check dimensions of application in order to determine appropriateness.
The intense brightness of the bulb is your payoff. It really does light up a workspace or living room. Low power consumption is the biggest payoff, 15w for a 100w light output. 'Corn cob' construction means it is basically a cylindrical structure with LED light sources aligned around the sides and top of the structure, allowing for a fairly wide angle of light dispersion.
Lifespan is another caveat. With a 50,000 hour rating, this light source could very well outlive me. -As if 15w vs 100w were not enough to pay for itself in savings over a single year, the device's lifespan is incredible.
So, if you like high color temperatures, saving electrical resources for a long period of time, not having to concern yourself with replacing a bulb for a looong time and have an application that can tolerate the length of this illuminator, Get this bulb
Pros: Feels good in hand, buttons work.
Cons: Horrible tracking, Poor fit and finish.
Other Thoughts: Aside from a fast scroll option, this mouse seems to have most of what you would need. But I dislike it the more I use it. It has the singularly worst tracking I have ever experienced (short of an old ball mouse impacted with dust on its' tracking axis'). At first I assumed it was due to a switch from a laser mouse to an optical, but then recalled an old MS optical I had tracked fine, and a current Acer optical I just used worked fine. This mouse tracks in jittery, stop and go infuriating stupidity. Forget gaming, it's barely suitable for mundane windows navigation. A mouspad helps a great deal, but even then, it misbehaves. Both with and without the supporting gigabyte software.
Then there's overall fit and finish. One reviewer noted a burr where the pinky comes to rest, and that's true. What's also true is the entire joint between top and bottom halves is sharp and shoddily put together. Not so sharp as it could cut the hand, but the edge has a FEEL that it could. The hand rarely touches this edge so it's not terribly noticeable, by itself, not a dealbreaker. But the horrible tracking is.
So, since I tossed the cardboard box it came in, I'm left with a 30 buck nice plastic box and one sad excuse for a mouse. Spare yourself the lost coin and buy something that actually works. As for me, I'm going back to laser tracking devices; more expensive, but worth it.
Pros: Comfortable, precise control, adjustable weight, response adjustable, surface indifferent, fast scroll
Cons: Braided cord is a bit stiff (tough though! : I've no cons for this one, other than current high price). Doesn't rotate my vehicles tires.
Other Thoughts: The GS500 was running for around sixty clams when I got it. Price dropped, I sent an email, got it for around thirty. :)
Could not be more pleased with a mouse. No obnoxious bright lights (even the sensing laser was invisible). The mouse read over any surface and adjustable weighting system made it feel substantial. After considerable use over an impressive period of time, left click developed a tendency to double click (tested on several PC's). My GS500 owes me nothing.
Current models of the old GS500 are running high in the price department, even so, a GS500S may be my next mouse. Currently running a gigabyte M6900...not terribly pleased.
