Salutations Tre93543,

It would be surprizing if you didn't have any ventilation, yet i'm somewhat worried about these CFL lamps as they must NOT be operated under hot/moist conditions since this could turn into a serious fire hazard, actually... I've been hopeful relatively to my own CFL lightning evaluation during the last year and yet i failed to realize that all along. Recently SpiderMites knocked my project down, i thought dryness could be a factor so i went shopping around for a humidifier. Since that's an open structure moisture level remained low, luckily!...

Now that i've pulled the plug there's some more time to read and after what i found i'd just prefer not to imagine what could have occured in a closed cabinet, while i was out of town!

Sorry if i sound demotivating, that's not my intent. But it seems none of the available technologies is 100 % suitable (always a trade-off to be made over heat, spectra, lifespan, efficiency, toxicity, name it!), etc...
