How about LED TL?

Post by **Digit** » Wed Nov 05, 2008 1:57 am

Today i had an interesting conversation with someone from a company that sells LED-TL tubes. My first thought was to go for tubes with ~3100 K color temperature, but i also mentioned that i now have Philips TLD 36W/33 tubes and wanted something similar in return. I was advised to order tubes with a higher color temp instead, so i did. I'll keep you all informed..

I'm anxious about your findings!

Today i installed the 2 LED TL tubes in my office. Conclusion so far: they're here to stay.
Light is different then from the old tubes. It tends to look more like daylight, actually.
It does look like i see more shadows, but not so much to be disturbing or annoying.
This is probably caused by the reflectors in the fitting not being able to do their job as well as with conventional tubes.
Nevertheless, i like them. Going to 'do' the garage too in due time when there's budget

Here some pics i made during installing:

Good to hear!
As the pics show they are more white (bright) then the old ones
which color temp do you have?
Prices keep dropping

Color temp = 5000K.
These tubes are available in 3500 - 5000 - 6000 K, all same price.
Oh, and i really like not having to wait for the lights to finally turn on

humm... I didn't know there were LED lamps in "fluorescent tube" format...

I still have severeal tube lamps, but fortunately they all have modern electronic ballasts, making it turn on immediately and worki without no noticeable flickering. (i'm very sensitive to flickering...)

At work we're finally starting to work with high power leds, and it looks like finally LEDs can really start to be used for all illumination applications (until now I was planning on using it just for decorative lighting.

Just one question, if you use these LED "fluorescent" lamps, do you still need to use the high voltage ballast? Or do you connect it directly to 220V or any other voltage?
Also, can they be dimmed/brighten?

AFAIK (because that was no point of interest for me) they are not dimmable.

Yep, I have already seen your pictures meanwhile... (and used it on one of my posts on my portuguese blog - with link to your site, of course
