... the BEST PRICES available anywhere. By way of introduction, the photograph on the left shows 4 different GU10 spotlights as follows: (top left) 50W halogen lamp with a 40° beam angle; (top right) 7W Auraglow LED 30° ; (bottom left) 9W Dimmable LED 60° ; ( bottom right) 6W Edison LED 45° ; So let us first dismiss all claims that LED lamps cannot match a standard 50W halogen lamp while using a fraction of the power. As you can see, they can variously come extremely close, completely outshine them and be not quite there but probably close enough (and certainly well above a conventional 35W lamp). ... ... Also, despite many efforts to improve the light quality of CFLs many people remain unconvinced and dislike them for this reason. Other aesthetic issues with CFL energy saving bulbs include the fact that they are not for the most part Dimmable and that like regular fluorescent tube lights (from which they are derived) many folk report eye-strain and headaches from the flicker and there have even been reports of CFL's triggering epileptic fits. All the above issues with CFL light bulbs can be addressed one way or another ... ... that domestic LED lighting bring are clear: • Ultra low power consumption • Cheap to run (save electricity) • Climate friendly - convert energy to light, not heat • Incredibly long life span (50,000-100,000 hours) • Huge variety of white tones and colors • Very bright, clean light quality • Dimmable • Lightweight, compact and attractive to look at • Environmentally friendly - no mercury or lead Finding cheap electricity ... ... and therefore more energy to manufacture. Fourth, CFL bulbs have poor start-up characteristics (noticeable delay before maximum luminosity is achieved) and much reduced life span if switched on and off frequently. Fifth, are almost all CFL bulbs are not Dimmable at all, and furthermore cannot be used to replace halogen lamps (for example GU10 mains voltage and low voltage MR16 12v fittings). Sixth, CFL light bulbs contain small, yet significant, quantities of mercury vapour. Mercury, a heavy metal like lead, is a “neurotoxin” and extremely poisonous and damaging to humans whether ingested, inhaled, or simply in contact with the skin. It's all very worthy making ... ... GLS and LED lighting, follow the link for further details, but the short answer is that they are bad news on all fronts. Total cost of ownership of CFLs is poor (the full purchase and running costs taken together); light quality is horrid; they are bulky, ungainly and downright ugly; most are not Dimmable; energy efficiency is not all that great; and the cherry on top - CFLs contain toxic mercury vapor and are therefore hazardous waste. No wonder even the lighting industry itself is keen to get beyond CFLs and into a lighting technology that really can deliver safe, high-quality light that is low-cost, low-energy, low-heat, low-carbon ...
