Finally an LED bulb that effectively replaces a halogen bulb. It truly captures the equivalent of a halogen 50W. It's rare enough (at this price anyway) to be reported. I have tried many other, mostly bought on Ebay and direct from China, without finding satisfaction. Even with the announced major powers (9w). Flawless manufacturing quality. It remains to see if the life is to go. That said, it will be more easily imporatnte that the above models, which invariably end up giving up the ghost after a few months of use. To stick to the best in halogen lighting must take warm white model.
