LED light bulbs are now good enough

A number of my posts here regard my battle to replace GU10 and MR16 Halolgen bulbs with LED equivalents, via a short period of CFL bulbs. This has been successful, with all the 40 halogens having been replaced with LED some 5 years ago. My energy consumption has gone down and so has the amount of heat generated into the loft and ceiling space from the bulbs.

Since then I have kept an eye on LED full size light bulbs for ES (Edison Screw) SES (Small Edison Screw and Bayonet fitting bulbs, all of which are represented in my house. Until recently I had found the LED lightbulbs to have dimmer light and a cold blue tint, much as the first Halogen replacements had.

A few weeks back while in my local B&Q DIY store I saw a display of Philips LED Bulbs, some of which featured clear glass and a kind of internal perspex crown-shaped diffractor.

I'm pleased to say I have tied both in SES , ES and Bayonet form-factors and they are superior to the Compact Fluorescent Bulbs I was using in 3 ways :

1) Instant high quality light, no 5 minute pink warm up period
2) Slightly less power consumption than CFL
3) No toxic chemicals that have to be recovered from CFL inc. Mercury

Cost is between £7-£9 per bulb with both 40w and 60 w equivalents.

As My CFL bulbs fail, or in some cases before, I intend to replace the CFL's with these LED equivalents
