Compact Fluorescent Light is One Crispy Critter
EDN’s PowerSource Blogger Margery Connor has complained about her frustrations with premature failure of CFLs (compact fluorescent lights) in down lights at her house. To prove her point, in a recent post titled “Compact fluorescent lights: Not always the best solution” she offered this photo of the burned-out innards of a failed CFL. (Note in particular the brown scoring on the plastic base.)
To also prove her point, she shot the temperature of a downlight CFL in her home with an IR gun and got a reading of 160F at the base, while the table lamp CFL was at 120F — a temperature difference that those finicky little transistors in particular might find a tad unbearable.Tags: Flourescent light; Thermal management
