I'm looking at refitting a torcherie which takes a 500W
RX-7 halogen lamp with a 70W metal halide lamp instead,
and electronic control gear (Tridonic PCI 0070 A001).
Just wondering on the pros and cons of HQI-TS verses HCI-TS
lamps. As far as I have been able to tell from datasheets:
HQI-TS: slightly better CRI,
cheaper,
more stockists.
HCT-TS: better long term colour stability,
longer life.
Also, the Osram booklet I have on their Metal Halide lamps
says that some of the lamps require glass screens for UV
protection and/or lamp explosion protection, but it doesn't
say which lamps do require such protection. Does anyone
know if the HQI-TS or HCT-TS need any such screen? They both
have an outer envelope around the arc tube.
