I don't know about you, but I am finding it a bit difficult to get my head around light bulb comparisons between the old standard light bulbs, halogen, CFL and now the LED versions. Its only a matter of time before I get there, but as the newer bulbs are designed to last years, I shall probably forget next time around!
As each bulb blows, particularly the halogen and CFL versions, we are aiming to replace them with their brighter, quicker to 'light' LED cousins.
These chaps are not cheap, seemingly anywhere between £5 and £12 each depending on how bright they are. Although the chart below gives some ideas when trying to decide what you need in watt comparisons, it seems we now need to get lumens into our brains rather than watts!
Once you get that into your head, you also need to know what bases you have. Have you got a small or large Edison screw, do you have large or small bayonet bases, see here.
Final thoughts must then turn onto whether you need them to be able to dim or not. Ah well, just another thing to adapt to!
