REMTEC SYSTEMS "NO-WATT" "fluorescent energy saver"

REMTEC SYSTEMS "NO-WATT" "fluorescent energy saver"

I have never seen anything like this before, but about half of the 32 light fixtures I got today had one of these devices in it. It wires inline with only the blue wires on a 2 lamp RS circuit. Appears to have a little diode, a transformer and a capacitor inside. Picture of its insides in next photo. The slimline version has one blue in and one blue out.

I have no clue! I do not see how it "saves" power when it has a transformer inside?! Photo of its insides in the next photo. Running the fixture with it and without it produced no noticeable difference to me. I was using crappy 34 watt lamps that came in some of these fixtures to test with.

Interesting! I will have to play around with this thing a little. Did you see the photo of its insides I also posted?

Interesting! I've never seen anything like this before, it looks like there's some kind of choke, diode and, a cap inside it looking at your pic of the insides.

Weird. sounds like it's designed so you can leave one lamp out of the fixture?

Did you try measuring how much current the light took both with & without it, and with just one bulb?

Colored Flourescent's such as F40T12 Red or  Green or Blue are awesome, the modern 'white' ones are kinda boring...

I ran across a bunch of something similar many years ago. I don't recall the diode, but they did have a transformer and a capacitor. At least in mine, the transformer is just a 1:1 ratio isolation for the preheat voltage so that the cap can couple both sides and connect in series with the internal ballast cap. As a result, lamp current is reduced significantly. I never measured it, but lamps did look dimmer.

@xmaslightguy......I don't think this is for leaving one lamp out, however, I did see some 'dummy' f40 tubes (black-ender Westinghouse) at P&M Lighting and they basically were clear glass and had the cap inside. They would take the place of one of the lamps in a two lamp RS circuit.

According to the patent into I found, there was another design for these. That design used an expensive dry film cap along with the isolation transformer, and the diode was not needed. In this design, they dry film cap is replaced with a cheaper electrolytic cap, but the diode is required to make it work.

@xmaslightguy, no, I just got these fixtures yesterday evening (32 for $40!) and have not had much of a chance to play around with them. I can't tell any difference in performance, but it does say (in the info icefoglights linked to) it is designed so the fixture can be run with one lamp, but also "offers energy savings when running both lamps". I took them out of the fixtures I plan to keep. Most have vintage original GE and Universal full power ballasts! Pictures coming soon.
