NARVA BIO-VITAL LT 54W/958 HQ G5

NARVA offers LT-T5 fluorescent lamps in the
ranges EQ (efficient output), HQ (high
output) and short (short-rod lamps). The
lamps in the EQ series are used for cases
where there is a particular emphasis on high
energy efficiency. The lamps in the HQ series
are characterised by a high luminous flux.
LT-T5 lamps in both series achieve a maximum
luminous flux at a surrounding temperature of
35°C. The rated luminous flux (measured at
25°C) can even be exceeded through use in
closed lights. The average lifespan (3B50) of
the LT-T5 lamps is up to 35,000h. LT-T5 lamps
with wattages up to and including 13W (short
version) achieve an average lifespan of
12,000h when used with a warm-start
electronic ballast and of 8,000h when used
with a conventional ballast. LT-T5
fluorescent lamps in the EQ and HQ series
achieve an extended average lifespan (3B50)
of 35,000h when used with a warm-start
electronic ballast.
