is this a function of the color spectrum
or one of simple intensity (or lack of)?
I note that the GE "Bug Lite" (anti-insect) bulbs are yellow and claim not to attract insects - which implies a lack of blue and/or UV.
Conversely the bug-zappers use fluorecent tubes that look white-blue/violet to attract insect - again seems to indicate a strong blue or UV content for attraction.
Most "white" LEDs are actually blue-white and I would have thought they would attract insects
- so do they have some discontinuity in their color spectrum that manages not to attract insects?
or are they just not a large/bright enough light source that insects do not confuse them with a source of "daylight"?
Back to
Ultra brightness -
I have recently got the Ultra-G (if it makes any difference) and the brightness is what I'd call "bright enough" for almost all close usage.
It is certainly bright enough to walk in the dark by - indoors or outdoors.
It illuminates objects in a darken room very well due to its wide and useful/even beam.
It is bright enough to read a map or directions in a car - but not too bright that it would "burn" one's eyes.
To me - it's brighter than the Solitaire at any focus setting,
not as bright as a 2AA Mini-Mag when the beam is tightly focussed - but the light is whiter and much more useful due to its wider and more even beam.
It is just brighter than my 3 years old (but hardly used) white Photon II - and the Ultra-G has a wider more useful beam.
Overall the Ultra(-G) is a very useful close quarters task light - I have read it is as bright and some report brighter than the well-liked ArcAAA LE -
- and we all know that the ArcAAA is very likely to win the 2002 Lummies - so if the majority of the flashaholics here think the ArcAAA is "bright enough" - then it follows that the Ultra is also "bright enough" -
- just that the Ultra is larger due to the fact it uses a single AA cell - which also results in over double the runtime (tested at 11+hours) of the ArcAAA at full brightness.
