Down Lights With Or Without Ballast?

[donal5 0]

Hi All, I am wondering if any of forumers use Philips downlights (without ballast)? Any recommendation whether to use downlights with or without ballast?

The Philips downlights are more expensive, about $38 (2 bulbs 6 inch no ballast), whereas other brand with ballast cost $20+.

I talked to the person in lightnings.com.sg and he mentioned that ballast also consumed power, so talking about saving energy, without ballast is more energy saving.

But I am wondering whether the one without ballast will cause the bulb not to last long? Any experience with the ones without ballast?

Thanks

All fluorescent lighting MUST come with some current-limiting devices such as ballast, be it magnetic (choke) or electronic ones.

Philips sells E27 PLL lamps (aka tornado lamps) that comes built-in electronic ballast and will cost slightly more expensive. so it would appear that their bulbs need not use ballast. I am using their flicker-free instant-on philips tornadoes. so far so good.

Hi neubie, so you are using the Philips downlights with built-in ballast in the bulb. I am wondering if this can last long or not? Mind share your exp, how long have you had this?

I think the bulb is roughly double the price of the regular ones, ard $6. Is this correct?

Thanks

Apologies, my mistake, I am using Genie series 14W warm-white lamps which has a lifespan of >4 yrs based on average daily operating hour of 5 hours...

No problem, that's what I thought also as the tornado may not fit in 2 bulb socket. Thanks for sharing the info. I think I am going with Philips even at a higher price, as I only have 12 downlights.
