I wanted a replacement 35w light tube for a kitchen strip light and found that it appears to have become obsolete recently. I used to be able to purchase it in B&Q, Homebase etc., for around £4. I searched the internet and National Lamps and Components was one of the few websites I found that exactly specified the lamp I needed. I was somewhat off-put by the high price of around £12 each plus high postage cost, Total £26 for two lamps. OUCH! Left with little alternative but to have to change my light fitting I bit the bullet and paid the high price. However, on the plus side the lamp tubes arrived expertly and securely packed, in just three days and were exactly what I needed. So good service and product. Pity about the price!
