I bought a Everyready bulb for my bathroom which took about 20 seconds of flickering to actually work and after 6 weeks it just brook. I should have just this Osram to begin with, minimal flicker ( less than 2 seconds ) and is a little brighter as well.

Just installed. Lamp is good quality but only time will tell if it is worth the money.
I ordered this lamp replacement for my bathroom which came quite quickly by royal mail,it was packed well and is a much better lamp than my previous one which only lasted a couple of years.
Bulb a perfect fit and just what I needed. Well packaged and delivered on time.
Very quick and easy service from this company. I couldn’t get this bulb from my local retailers. I opted for next day delivery and was delivered around lunch time. The bulb is very good and gives off good light. I would recommend this if your light has the same bulb.
Items arrived safley and well packed. Great coustomer service. Thank you
Exactly as described. I haven't had chance to fit them yet but they arrived very well packed and less than 24 hrs after I ordered them. I had opted for the ordinary delivery service so such a swift delivery is remarkably good service.
The Osram 28W 2D Fluorescent Lamp arrived promptly and had been carefully packaged to avoid possible damage during transit. I have now installed the lamp in my bathroom and it works very nicely. Thank you.
