Repti-Glo badged C.F.L.i

Repti-Glo badged C.F.L.i

This colour 840 C.F.L.i is interesting in that it claims some U.V.-B (and A) output suitable for reptile basking. When powered up it looks just like any other colour 840 C.F.L.i.
I have seen a lot of U.V. lamps (lit) in my time, everything from germicidal tubes to Wood's glass U.V.-A to Electrodeless Inert Gas Excimer lamps and the fluorescence they tend to excite in all sorts of things....this does not seem to exhibit fliorescence excitation to amy greater extent than a "normal" colour 840 TriPhosphor lamp...and that is what the handheld spectroscope reveals despite the pictorial representation of the spectrum on the box that suggests otherwiise.

The 840 color might be brighter than any fluorescence it might cause. Maybe the fluorescent materials aren't very sensitive to UVB.

There is a spectrum in one part of the box, which shows a strong wide phosphor band in the UV. Is it really exists in the spectrum of this lamp?

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

Does it exhibit anything transmittance of the UV-B using the existing glass material?

Pretty, please no more Chinese failure.

Actually it was quite dim, but I did not really give it enough time for the mercury vapour pressure to come up.

dor, That is the "64 million dollar question" only a spectrometer will answer!

Robert....yes I think the glass starts to extinct below about 320nm and is totally black by 300nm. But is the absence of that spectrometer....with a $3000 price tag...this re-badger will be able to make all the claims he likes and none of us can really challenge him!

One way to find out if it has UV is to get a reptile, and then see if the reptile behaves like there is enough UV.

No, just whack a bit of Wood's Glass in front of it and put various fluorescent things behind the Wood's Glass and see how they react, or better still, spend the US $4000 and get a properly calibrated Ocean Optics USB Spectrometer!
