New UVL T5 with internal reflector

[xcaret]

Any input on these little things?

Thx

a t5 with an internal reflector? You sure about that?

Don't think I'd like an internal reflector, they're too small to really be useful

Where does it say it has an internal reflector?

I came across it by looking at MD home page and saw the posting T5 VHO-R. I think there´s a company too making PC´s with internal reflector

They are basically applying the same principle on their t12 VHOs to t5s.

Ignoring the reflected light explicitly, from a technical standpoint, there is a new interesting facet of having a lot more photons re-striking a phosphor at a new wavelength. Curious to how this shifts the net spectral output.

IC now. You linked the wrong bulb.

I have a couple of those UVL super actinic bulbs, but I'm pretty sure they don't have internal reflectors.

They have a new line of their old bulbs (and a new 454 bulb) with internal reflectors.

I´m going old school with VHO´s to see the difference in color with super actinics but I might try these in a couple months; frees hipping four or more !

these would be nice if you didn't have individual reflectors but won't have nearly as much output.
