So far customers have been either early adopters, or needed the small size to solve a variety of install problems. Carnival Cruise decided to try some because of their space constraints, and CBS news in NYC bought a bunch when they found out they had less room in their new custom studio fixtures than they thought. The 8-packs have been popular with rental houses. Altman carries Brickblasters now for example:Those seem like an interesting product, has anyone used them before?
RickR alluded to this, but the code issue is that, more than just during a power loss, you need "panic" lighting. Basically "it" hits the fan and the house lights go on, to full, ideally white. At our space our racks are tied into the fire alarm so when the alarm trips the lights go on. No evacuation in the dark, EVER.

I may have been mis-read. The all-on panic lighting is in addition to the battery units, or genset, or inverted. Fire breaks out, power stays on, you may have evacuation in the gloom.
They're barely audible at all. The fan that's used is a low noise computer case fan that's powered at 8V instead of 12V. It's pretty big (85mm), so running it slowly still moves some good air. The result is a nicely cooled 4" cubed 50W light, and you wouldn't know there's a fan at all, unless you get right up to it and listen carefully.These look quite nice - but they do have a fan. Has anyone had experience with the unit and can fill me in on how noisy they are?

I'm curious about the "loss of DMX" feature... I get how it's intended to be used, but I'd think if it's really going to be used for "emergency" use, they'd need to be certified for that.. like UL924 for example. The problem is.. an emergency lighting system (using a light with this feature) needs at least two other system components, an un-interruptable power source, and the DMX source that feeds the light... so would all these components need UL924 if this system was the "sole" emergency lighting system?Affineon makes some nice looking fixtures. The downlight series gets to be pretty bright. They are probably too bright and expensive for your use unless you redo the whole system.
On the code note: they can be set to go on when DMX is lost, for emergency conditions.
I've had demo units but haven't seen them in action. I will in the next few months if the installers get moving...

With traditional emergency lights, the power source and light are combined into one unit, and they're triggered directly from power loss, so I can see how this could be agency tested. But I don't quite see how a system with distributed parts could end up being UL924 listed.
Not sure how to respond to this implied judgement, but the fan used is not "crap".. it's a quality 35,000hour, long life fan that we're running at half it's nominal speed... the fan is gonna last a long time. Additionally, the electronics aren't going to "cook".. the fixture measures it's internal temperature and shuts down if things get too hot (pretty sure I covered that in my earlier post). That being said, of course convection cooling is better, there's no fan to fail... but good luck finding a convection cooled 50W 4" cubed RGBW LED light that delivers 1200 lumens or a 50W 4" cubed all white (WNC) light that delivers 3100 lumens... that level of lumens/size performance is amongst the highest in the industry, and requires forced air cooling. So.. yeah, if you don't need that lumens/size performance, there's quite a few convection cooled lights to choose from, but if you need the smallest brightest light you can find, this is it... and did I mention that you almost can't even tell there's a fan, even when you're right next to it?I maintain a ton of broadcast grade equipment with cooling fans. The fans range from cheap to expensive, sleeve bearing to ball bearing. Trust me, you absolutely do not want a ceiling full of lights with cooling fans. In a few, short years, it will turn into a collosal maintenance headache. Fans are simply too unreliable, especially the crap made for the computer industry. They'll be making all sorts of obnoxious noises when the bearing start to go, and then freeze up causing the electronics to cook.

No problems with opinions on feature tradeoffs and application appropriateness, everyone's entitled to his own, some more than others, based on their knowledge and experience.I'll stick to what I said before, based on 25 years of doing electronic maintenance. All fans are a high failure item. They are a reasonable and necessary tradeoff in LED stage lighting where compactness and light intensity are important. In my humble opinion they have no business in a house light when there are better alternatives.
35,000 hours is a really long time for a stage light. In some facilities that time could fly by in house light use. It's roughly the equivalent of three years of continuous use. Stage lights tend to be used hard and replaced fairly often. A house light should be able to do its job for 30 years.
