Red 5 watt LED and night vision?

oldgrandpajack · Dec 4, 2003

I've read that red is good for preserving night vision. I've also read that dim red is best. What about a 5 watt red LED in large open spaces like hangars, auditoriums, stadiums, warehouses and the great outdoors. I recently bought a Surefire L4-HA-RD and hope I didn't make a mistake. What do you all think? /ubbthreads/images/graemlins/icon15.gif

PS: I have a F04 Beam Shaper waiting in the wings, to eliminate artifacts, if needed.

I didn't know Lumileds made 5 watt in Red... Is this a modded L4?

Hi Jon:
It may be a misprint on the color. I will be happy if it is white, but when I saw it listed as red, I jumped on it. Don't know anything about Lumileds production of red 5 watt LED's. It is not modded. It was listed as NIB. I will let everyone know when I get it. Usually takes about 7-8 days for shipping (UPS Ground). /ubbthreads/images/graemlins/frown.gif

Lumileds does not make a 5W red. They are either using a color filter, or are incorrect about the LED color.

If it's a filter, you'll be sorely disappointed, since "white" LEDs generally put out very little red light.

unless it has a red 1w in it, in that case it should have good throw with some nice side spill.... wonder if it's official SF or modded?

oldgrandpajack,

I just checked out the eBay sale in which you got that light. Since it's NIB, I suspect that it is indeed a white -- a mistake in the listing by the seller. In either case, you got it for a great price. Congratulations.

I got it yesterday and it was a misprint. I am still happy, as the price was right, and you can't go wrong with a brand new, sealed in the box, Surefire L4-HA-WH.
