5.0 out of 5 stars Bright 4 Mar 2011
Verified Purchase
I have various downlighters that use 12v Halogen bulbs. The one's in the kitchen get alot of use and I have tried various brands including very cheap ones. The cheap ones such as poundlound are a waste of time - sometimes they have blown as soon as you switch them on, but normally only last 3-6 months and it seems I was always replacing them. So I started to monitor the brands and how long they last and how much they cost. Yes its a sad life I lead. I found the Philips lasted about 2 years at about 3 each from places like Sainsburys and B&Q. So decided to look for a better deal on-line. I found the Philips (2,000 hours), but then saw these Sylvania 4,000 hour bulbs for about the same price - so a no-brainer. The proof of the pudding will be whether they last 4 years...
What I can say now is that these bulbs are noticeably brighter than the other bulbs in the same room so that's a bonus and hopefully an indication of build quality.

not much else to say, they do exactly what they need to do and the price is pretty reasonable for the amount you get.

I buy these as it is unusual to get such a wide angle beam that spreads the light over a greater area

4.0 out of 5 stars Least Expensive but do seem to blow frequently
This particular Halogen Dichroic Reflector is the most competitively priced, but they do seem to blow very frequently in my kitchen!

5.0 out of 5 stars Wide angle, superb light
These bulbs give wide angle, clear light. We use them in the hallway and on the landing. Some bulbs give a narrow beam, but these are just perfect. Good value, too.
