    CFL Disposal: It's In the Bag

    By Posted on 7.10.2008 5 Comments

    Compact fluorescent light bulbs solve one problem, but present another: Although the bulbs are longer-lasting and more energy efficient than incandescent bulbs, CFLs contain mercury, a neurotoxin. If a bulb breaks or isn’t recycled properly, the mercury can be released into the environment.

    This is good to hear. I've been thinking a lot about CFL bulbs and their mercury content since my parents in Georgia recently experienced a massive power surge (throughout their entire neighborhood) that resulted in every light bulb exploding. The absolute first thing that came to my mind was mercury contamination from CFL bulbs. If many of those bulbs were CFLs, that's a significant amount of mercury exposure and contamination. It's good to hear that this new selenium-based material can absorb such a high percent of mercury spills.

    For the vast majority of us, few are the occasions when our opinions matter in any meaningful way. Say what you will about the importance of teaching your children, or being in charge of your office budget or participating in the voting process, but the sad reality is that your wisdom is an underutilized asset… except when it comes to your tech savvy. If youre reading this, its your responsibility to go out in the world and evangelize against the temptations of bad tech gear.

    As a former sales manager at a major consumer electronics retailer, I can confirm that the two priority items that our sales staff was pushed to sell were accessories, such as Monster Cables, and extended warranties. If extended warranties didn't make up at least 5% of your total sales, you didn't last very long. In fact, my monthly bonus was heavily impacted by the sale of those two items. Why? Because as the article states, these items have very high margins. On the daily sales reports, extended warranties came up as 100% margin. As far as new scams are concerned, I believe it has to be the ISF calibrations that many consumer electronics stores are currently pushing at roughly $300 a pop. I had never heard of it until a couple months ago when I stopped into a BestBuy. There, I stood and listened as a sales associate went into his long spiel about how all new HDTVs leave the factory completely out of calibration because they're adjusted to standout on the showroom floor. But luckily there's a way to correct the problem; just have one of BestBuy's ISF certified calibrators come out to your home and spend an hour or more calibrating your set to exacting broadcast standards and your own unique lighting situation. Per the certifying authority - isfcalibration.com: "A Basic ISF Calibration includes adjustment of Scan Velocity Modulation and electrical focus, touch up of convergence and calibration of color temperature to 6500K." "Cost of a Basic ISF Calibration is: $245.00 + $45.00 each hour of travel past the first hour + sales tax." "After the initial calibration of the display, touch up adjustments should be performed every 6 to 12 month or when you feel they may be required. This will all depend on the usage of the display." Wow! Just $300 every 6 to 12 months to keep your TV set calibrated - nice racket.
