eBallast vs normal Ballast

[aqualover]

I just want to gather some statistics - For those who have switched to using eBallast :

1) Do you really find your lightset much cooler than what you've read on the web or expected?

2) Does the energy-savings perform up to expectation? In other words, does your electricity bills drop by up to 40% as claimed?

So far, what is truly apparent is the advantage in weight, but for point (1) & (2), does it really live up to expectation or is it just hype?

size should be the next problem, metal ballast support one tube only....

>> 1) Do you really find your lightset much cooler than what you've read on the web or expected?

Yes. Cooler. At least not as much heat generated by the ballast.

>> 2) Does the energy-savings perform up to expectation? In other words, does your electricity bills drop by up to 40% as claimed?

Hard to calculate as our total electricity bill involves so many appliances at home. The air-con and fridge uses the most power.

Where did you read 40%? Which brand of eBallast are you using?

several reputable websites that are dealing with lighting equipment.
I'm using 55W E****u PL eBallast with 55W L****a PL tube

the claim is meant for energy saving lamps with built-in electronic ballast. could be true if compared with incandescent lamps.

may not have that much savings if you compare magnetic core ballast with eballast. there are some savings when you use eballast by virtue of eballast is running cooler that magnetic core ballast. cooler means less energy wasted in heating the magnetic core.
the advantages of eballast are
a) no humming sound
b) no flickering of light during startup
c) runs cooler

I'm using T5 & eballast as well. Cooler definitely! Energy saving, can't tell.

One other "hear-say" fact is lamp life lasts longer since there is no flickering during startup. Can anyone confirm this?

Based on some document I read from Philips. Yes. Its true that e-ballast is recommended for T5.
