4000+ Lumen Test & BridgeLux LED Review

[bozola]

Re: .·´¯`·-> !! 4000+ Lumen Test & BridgeLux LED Review!! <-·´¯`·.

I've been playing now with the 400 lumen stars. It's taken a while to figure out all the little details of power control, heat, and enclosures. The learning curve ain't so bad and I can honestly say that this has been a seriously fun project.

What I'm after is a stupidly bright set of off road lamps for my Russian Ural sidecar motorcycle. I've already got a spot light. I've already got fog lights. They aren't enough.

I'm about road test some enclosures based on the BRIDGELUX BXRA-C0400-00000, a 700mA BuckPuck, a 10w passive heatsink, and a really cheap aluminum Chinese enclosure.

Thank you Nessus for starting this thread. It's changed my life.

Did this thread die? Has anyone found a found a lens that would work to make a tight beam? I wanted to try it in a projector that I have already gotten to stay on without a bulb. I was looking into using a p7 with a lens but then I found this.

I'm glad that you asked about optics. It inspired me to take another look.
I don't know how I missed this before!

HERE is the a link to:

Here is the important part of that document!!

Thank you. Nice find. I emailed LEDil about pricing for the 24 degree for the C2000.

 

[zeramant86]

Itchin to see some creations with these.

I emailed LEDil about pricing for the 24 degree for the C2000.

Yeah! I could do some interesting things with that.

One helluva disco-ball light at the least :huh:

Curious about pricing.

I've asked Anderson and they couldn't get a response from Ledlil- this was almost 6 months ago. I've mailed Ledil a couple times too and never heard back from them.

They might be selling the Bridgelux optics, but I'll be damned if I know where to get them.

 

[blasterman]

Also note that Bridgelux is now selling a 5000 lumen array.

too strong!

Maybe this will be the first LED light to boil water.

On a serious not I think that one of the big applications will be house lighting. Obviously brighter than those multiple 5mm led models and still better than the 3xQ5 style models
If someone were buying these LEDs wholesale im sure you could get a 1,000-2,000 lumen bulb for less than 60 bucks. I would buy that.
A lot of house lighting bulbs for medium rooms output in the 1000-2000 lumen range so this would definately be competition.
With the flood, maybe some thin lamp shade to spread out the light!

Anyone here know how to turn the 25 die LED into a basic household lamp? If the price were right I would even buy one from someone here who started making those!

Hmm.. Wonder how I can make this work.. What If I use the built in Reflector of the existing bulb?

I realize that we are focusing the bulb through the aperture on the LCD.. so a tight beam is ideal, right? Or am i going to get one big hot-spot?

You want the straightest throw possible. In the case of LCD Projectors they use a flyeye lens array to homogenize the light but you still want it fairly even.

These LEDs that are arrays of single dies do not work as well as a SST-90 in combination with a ~50mm Aspherical lens as you cannot get nearly as much light straight (collimation) as you can get with a 3x3mm source. The lens I find that works best is from KD the 52mm exotic.

This is perfect! I've been looking for a way to see my bacon and fry it at the same time.

Been experimenting with such. Because of the built in directionality and efficiency of LED it really only takes about 800 lumens to fill a room if you do it right. I've been working with diffusing the light by upfiring and bouncing off of a diffusion panel or white umbrella. The light is utterly glorious.

The Warm-White versions have awesome / perfect color. They are superb for living room lighting.

The 5000lumen version is generating some excitement in the reef community because it can displace a 250 watt metal halide.

Are you able to build such a house lamp assembly? I would pay for it. Probably make my own shade and stand but the electronics I dont know how to do. Last time I went to radio shack the people there did not really know anything about all the various electrical components...

 

[blasterman]

I use conventional external power sources like laptop bricks, Xitaniums, Meanwells, etc. Keeps the design clean.

For your house, which uses AC power, you have to convert it to something usefull for an LED. You could build your own power supply with base components or you could 'keep the design clean' as blasterman puts it, by using a premade AC-DC converter. I'm using an old Sun monitor brick for my desk lamp. 😛

Gotcha there, but you would still need to make sure it had the right voltage in DC right? I dont know how to build that kinf of thing. I could follow simple directions or I could buy one from someone.

 

[blasterman]

Gotcha there, but you would still need to make sure it had the right voltage in DC right?

Example: I have a box of 18.5 volt laptop bricks. If I run five LEDs in series they get 3.7 volts each. That's 700mA for most 3watt white LEDs. Or, if I run six LEDs in series they get 3.1 volts.

If I run two smaller Bridgelux in series they get 9.25 volts each. I don't need a custom power supply.

 

[jtr1962]

I'll add that even though LEDs strictly speaking should be run on constant current, rather than constant voltage, supplies, if they are adequately heat-sinked to prevent thermal runaway, then they can be safely run on a constant voltage power supply.
