Osram vs Elbiru eballast

[AnA]

I have tried the Osram's and Elbiru's eBallast as below. Notice that the Osram measured 108watts and Elbiru measured 78watts when using them to drive 2x54w T5 tubes.

The ligthing brightness from both eballast is about the same but if see closely, Osram seem to produce slightly brighter light. Only sligthly.

For a saving of 30watts, think using the Elbiru's eballast seem better.

You can't use your eyes to gauge the brightness per se. You would need a PAR meter to differentiate both e-ballast output for the light tube.

Agree we need special measurement tools. But, I have no choice as I do not access to such tool. Anyway, Osram eballast like this one has some other benefits which the normal elbiru eballast does not have. Features like pre-heat, auto shutdown when detect faulty tubes, lesser distortion...etc.

thanks.

Osram eballast rated 108W.
Elbiru eballast rated 78W.

Both tested on 2x54W tubes. Seems like the Elbiru is "underpowered" for this. Maybe this could explain the dimmer lighting?

Maybe Elbiru is really "underpowered"...but, the brightness between the two does not seem to be of great different. Again, I do not have brightness tool to do the measurement; just use naked eyes.

Osram Quicktronic and Tridonic eballast...cost $40-50
when on it gives a slow start light-up of the T5 Tubes
thus prolong the lifespan of the tubes..

while using Elbiru eballast...cost $20...
it gives a instant light-up on the tubes..
so the lifespan of the T5 Tubes will be shorter...
correct me if i am wrong

Yes, troyz, you are right about the Osram Quicktronic has a slow start (Pre-heat) feature.
