## Questions & Answers

**Q: my old tube measures 450mm fromend of pins  will a 18inch tube be ok**
A: 18" is equal to 18 X 2.54 = 45.72 cm or 457.2mm.  This is the correct length.  Regading color temperature 2700K-3200K is the incandescent light (beige-like), the 4000K is the natural daylight and  5000K - 6500K is the ice white (like that of a flash).  The letter "K" regards measurement in Kelvin degrees.

Sylvania 18" 15W C835 White fluorescent tube.Fluorescent tubes are staring to get rarer these days since their manufacture is now banned and they are being replaced with LED tubes. The problem is, an existing light fitting may not support LED tubes as a direct replacement, without modification.I have a bathroom mirror that is internally lit with two of these tubes and they both needed replacing. None of the usual places locally had them in stock, but luckilly they were available on Amazon. Sylvania is a fairly common lighting brand name and I have had their tubes before, so knew they would be OK.
