Frequently Asked Questions about Lupo Lighting
Lupo DayLED Spotlights
What's the difference between Lupo HMI and Lupo DayLED?
“An HMI lamp uses mercury vapour mixed with metal halides in a quartz-glass envelope, with two tungsten electrodes of medium arc separation.” – Wikipedia
The noticeable difference between a Lupo LED light and a Lupo HMI light is that it takes about three minutes for an HMI light to reach peak brightness and correct colour temperature, just like a data projector. During this warm up phase the colour of the light will vary slightly. Once lit, the light will continue to burn for as long as you need. Once switched off, a Lupo HMI 800 will not ‘re-strike’ for about four or five minutes until the bulb is once again cool.
The lamp life of an HMI unit is over 12,000 hours, which is very good but cannot match the reliability of LED units (50,000+ hrs). Having said that, the Lupo 800 HMI is still extremely resilient, so you need not fear about the bulb blowing if switched on while still hot.
How do Lupo DayLEDs spotlights compare to Arri tungsten lights in terms of light quality and usability?
Lupo spotlights use the same fresnel lenses as Arri tungsten lights. The powerLED used in Lupo lights are circular in shape as opposed to the filaments used in Arri Junior fresnels and, as a result, produce a cleaner spot.
It’s worth noting that Arri lamps will blow from time to time whereas Lupo LEDs will last a lifetime, rated to over 50,000 hrs. Arri tungsten lights run hot, draw a lot of current and can’t be run off of a battery. When dimmed, the light output will also appear redder.
Conversely Lupo’s run cool, maintain their colour temperature whatever the dimming setting and can be powered by battery due to their low power consumption. Lupo DayLED’s are available in 5600K daylight, 3200K tungsten or variable (dual colour).
Users of fixed 5600K Lupo lights can work with filter gels to alter the colour temperature of the light. It’s much better to warm up a cool light source than cool down a tungsten light using gels. This is because orange gels are half the density of blue and results in far less light loss.
Do the lights flicker as you dim them?
There is no visible flicker on Lupo DayLED lights and you can use them for stills or video at all normal settings. They are certified flicker free for up to 12,000 frames per second. For very high speed video application we would suggest running the lights on full power.
Do Lupo DayLEDs lights make any noise?
The Lupo DayLED 650 and 1000 operate in complete silence.
The Lupo DayLED 2000 does have a quiet but audible fan built into the unit. For those conscious about removing such background hum, especially over dialogue recordings, we would recommend using an audio editing tool like the Dialogue Denoiser found within IZotope’s professional RX5 Audio Editor.
