I have long been an advocate of their products. THey produce a good (albeit very expensive) bulb that has been hard to tell it was a LED. However, I recently purchased two more Sensibulbs and have to tell you that thehy have changed their manufacturing. The new bulbs give off a blue light versus the very pleasant warm, yellow light that they were known for. This blue light reminds me of a flourescent and will come is very sharp contrast to other Halogens or the older Sensibulbs.
I contacted Sensibulb and they did indeed tell me that they have changed their manufacturing. There were a number of reasons for it, but the bottom line
is that I do not believe we will be seeing the old bulbs any more.
You will be able to tell the old from new by a simple glance at them in the package. The old LED's will have two
'yellow' looking LED's versus the new ones which have a single
'yellow' LED. There really isn't much else to tell from the package that will seperate them. But once you plug them in, you will probably be able to tell a significant difference, especially when placed beside Halogens or older Sensibulbs.
Basically, anyone considering a purchase of this product, shoudl be aware of the changes as they will no longer match your other lights
. And if you decide to replace all of the LED's, they will put out a 'blue' hue which is very undesirable to me (others may be fine with it). But given the extraordinary cost of these (nearly $40/piece if not more), I would certainly entertain looking at the many other LED manufacturers as there no longer appears to be any difference between them... or just stay with your old Halogens until a suitable warm LED comes back on the market.
PS I wiill try and shoot some pics this evening to illustrate the difference... it is just daylight now so I cannot do it.
