Compact "D" style 4 Pin lamps are commonly used in commercial and some domestic luminaires such as downlighters, bulkheads, pendents and other suitable energy saving applications.
“This particular lamp was a compact fluorescent but it was unbranded and NOT Sylvania. Although it will hopefully do the job for my customer I am not overly confident in providing unbranded products. I was charged the price you would normally reserve for a branded product so I would expect to pay less for an unbranded product such as this.”
