Hello Wrenches,
We tested some Brand X T8 LED's two years ago. They've all burned
out.
We're now using Phillips "Enduraled" T8, 22W 120V lamps.
I'm confident that they will respond to warranty issues when they
arise.

I did notice one thing when I converted my shop to LED. One of my 4' flour
fixtures was a plug in type so I used my kill-a-watt and plugged the fixture
in, with the ballasts and T8s and recorded a usage of 48W. After removing the
ballast and installing the LEDs (21W each) the kill-a-watt read
I recently built a new home for myself, earth bermed and of course,
solar powered (and soon to be solar heated). Every light source in the
home is LED. I did a lot of homework, testing bulbs and different
fixtures, and am very happy with all of what I decided on. Kitschler
makes excellent,
If you have never looked at LED panels, do find a sample to try. The 30cm x
30cm panels give a steady even light from a 1/4 thick panel. For under
counters, dropped ceilings and work areas, they are just lovely. I expect
to see a lot of creative uses for these in the near future.
The brand of T8 LEDs I have in my shop is Neptune. When I purchased them them
website had buy American compliant but they say made in China on them.

Hi, Knuckle-Busters~
It's lighting retrofit time and also time for me to review what I thought
I knew about various lighting technologies.

Round one of the conversion involves well known RV brand T8 tubular
fluorescent fixtures (3' long single tube). These have 24vDC
Mick,
I ALWAYS go with AC lighting. The cost/watt of the extra power to operate AC
lighting is minimal compared the the hassles you have, and will experience
again, trying to go DC. If the customer needs lighting to be always available,
go with a small dedicated inverter for the light circuit
here in mount shasta woo-woo land, there are loads of folks who hate
fluorescent lighting (never mind that they never notice fixtures with cfl's in
them). they are all smiley though about leds (go figure).
my experience with leds is the lumens/watt is still no greater than a good
cfl/hid
I have the T8 LEDs in my house and garage, I've had them running for a year or
so, I'm not home to check the brand, but I really like them for the shop,
especially come winter. I'm by no means a lighting retrofit guy, so maybe I
just bought into a tech to soon, but they seem to work good for
You know, what baffles me - and may be
the reason for the generally-accepted view that LEDs have really
high efficiency - is why LED Christmas lights use so little
energy. I have a couple of strings over our front porch that we
never turn off, day or night, at
The fixture - and putting the correct lamp into it - is more important as
efficiency IMO. Some lamps burn out very early in the wrong fixture.
My recent article in the Huffington Post sums up my view:

Hey Dan,
Great point. You just reminded me of the PV solar powered billboard lights I
installed about 2 years ago. They are 120 Vac, 50 watt LED floods. So far they
survived two Yuma, AZ summers with temperatures above 115°. During my studies,
I learned that heat dissipation by the fixture was
I don't know anything about RV systems but as to LED lighting in general,
we recently sold and installed 130 LED fixtures in a large villa to replace
MR16 lamps, saving the client over 6KW of load. The light output is better
than the MR16, there is no heat, and they were very cost effective
Hi
In Tunisia there is a net zero energy retrofit project in 4 health
facilities. The exisitng lights were mostly ceiling mounted 34 W
Flourescent tubes and 20 W tubes. We replaced them with 20 W and 10 W LED
tubes. The LED tubes are more like task lighting that directs the light
onlyt downward,
the Fluorescents: What about LED tubes for late
2012?

I have several LED lights, mostly AC, and I'm a big fan.
The light quality approaches that of halogens, and the watts are
noticeably lower than CFLs.
I have spot lights, floods, and rope lights that I forget to turn off
because I can.
LEDs have come along way in the past year.
