If I replace a fluorescent with an LED T8/T12, will I get as much light in my garage as the fluorescent? The LED tubes are only lit up on the bottom versus all the way around on a traditional T8. I was just wondering if the LED would light up the garage as much. Thanks.

Can you provide some more info? As bdamic stated, lumens of each light fixture type is going to be a good starting point.

No, check the web for the DOE fact sheet wrt T8 LED replacement lights...

I don't think LEDs are a mature enough technology yet to replace florescent.

Yes, they'll last longer, but at their current prices they are way to expensive to make them economical.

Depends on the manufacturer. Most LED bulbs aren't as bright as what they claim to replace.

LED is directional, so you don't lose as much light to the fixture/diffuser/ceiling. You can get them at the perfect beam angle and the perfect spread to get exactly how much light you want at a certain point. In many applications they really do make better use of the lumens they put out.

Problem is that T8s are incredibly efficient and their large bulbs spread a lot of light. If you're in a shop where you don't care about ugly fixtures, fluorescents are hard to beat.

Yes, very diverse and very good at light distribution. Based on physical size between fluorescent and LED, much more light out of fluorescent. Then you have the high cost issue and heat issue of the driver. Another thing frequently misunderstood, LEDs will last a very long time, but the drivers that power them are the weak link and cause of most failures. The less room they have to breathe, the lower the life. I firmly believe LEDs will be the future light source of this country, but we still need 10-15 years to get there.

I don't think it's going to take 10-15 years. It just depends on the manufacturer of the LED. Philips has an excellent reputation and have been shown in torture tests to hold up very well. And I recently got a case of the Philips three-lobed LEDs, honest-to-God 60-watt equivalent, standard bulb shape and profile, to try them out. Much better light than fluorescents, come on almost instantly and at full brightness (eat your heart out, CFLs), dimmable, and use only 12 watts (the new and more expensive model uses 10 and puts out 70 watts of light). Cost was only $14 each--that's already paying for themselves in two years, probably less in the applications I have in mind. Yeah, I could use CFLs, and probably save money overall, but I like the quality of the light from the LEDs, the dimming and the instant full brightness. That's not to say they don't have a ways to go. They still don't have a hundred-watt equivalent LED that fits in a standard profile.

I noticed Lowes is selling 1400-lumen par38 bulbs for less than $40 each, I might give them a try. What a novel idea--energy efficient outside lights that actually come on instantly. Can't imagine why you'd want that, eh?

But as far as shop lights go, LED doesn't have enough advantages over T8s to make them worth the cost.

I am lighting my shop over the last couple of days. I checked the price of LED fixtures and they were several hundred dollars / fixture.... I went with 16 four foot T-8 Lithonia fixtures @ a little more than $40 each. I wanted LEDs so bad but now way to afford that.
