Looking for lamp with red led as well as white or a red diffuser

Other Types of Lights LED Headlamps
1

I have a number of good quality headlamps but none have a red light.
I have tried to find a red diffuser to put on my existing lamps with no luck.
Any suggestions as to a lamp (18650) or diffuser ?
I don”t want to attach red film to one of my existing lamps as I need to be able to use the white light as well.

I guess I’ve seen some lamps being reviewed here with those red leds, but I can’t remember the names, nor if they are 18650.
For the diffusers, you can take a look at these from Kaidomain

Hope it helps :wink:

Nitecore has some headlamps with red LEDs

Unfortunately those diffusers are all way to big diameter wise.
My Nitecore HC60 which is the headlamp I would liked to have used would need a push on diffuser with an id of 18.45mm.
I have just ordered a flip down diffuser for an old Fenix HP10 that I have which I am going to put some red film on it that I have & see how that works.
By being flip down it does give me the option of the white beam or diffused red light.
The down side is that the HP10 is a 4 x AA cell light not my preferred 18650 cell & is only 225 lumens on turbo & that steps down after 3 minutes.
The highest lumens you can maintain without step down is 140 & with the diffuser & red film I don”t know how bright this is going to be.
This light is for night lure fishing where the fish will be spooked by shining a white light on to the water but I still need to see what is going on when casting & retrieving the lures.

I have a Nitecore NU30, wich is nice with red led. Good u.i., low weight and rechargeable with micro usb. Fairly good runtime too, I like it.
But not 18650 and after about 5-6 weeks it needs a recharge due to parasitic drain. Still the best headlight I could find with red lights yet. Would still jump on a 18650 version without the drain issue.

The Nitecore HC50 has Red LED’s

  • 18650
  • 2 seperate Red LED’s(not just a diffuser) with direct access to RED light mode

What sort of distance would red light be usable at ?
I have always night fished with standard white light headlamps using either an Olight H35 Wave or Nitecore HC60.
I would be bottom fishing at 100 plus yards so no need to worry about the light spooking the fish.
With this lure fishing I am generally fishing on the surface at distances up to about 50 yards hence the white light would spook the fish.
So I want to be able to see my lure hit the water at say 50 yards & then be able to see it as I work it back to myself across the surface.
A red lens would, I imagine, be the answer as it would allow the lamp to retain it”s beam profile & just put out red light instead of white.
Unfortunately I can”t find any red lenses that will fit any of my lamps as they are all to big.
I think that any type of diffuser will just spread the beam & only allow me to see close up ?

EDIT:
Whilst on the Fenix UK site I noticed that they do a 40mm ID push on red lens which is to way to big for my HC60, RJ-02”s, Hp10 etc.
I then remembered that I have a few cheap Chinese no brand zoomie headlamps, claimed Cree XML-T”s & 3000-5000 lumens but in reality latticebright led”s & probably 300 lumens.
However the bezel”s are 38mm so I have just ordered one of these Fenix red lenses (costs more than I paid for the Chinese lamps) & with a bit of tape or similar to build up the bezel diameter I should be able to get a snug fit.

Well the 40mm Fenix push on red lens arrived.
I wrapped some insulation tape around the bezel of one of my cheap chinese zoomies to build the od up to 40mm & got a snug fit with the lens.
Unfortunately when I used the lamp it was just not bright enough for my use.
So I am back to square one.
I need either a red headlamp that will light up objects at about 50m distance or a red lens that will fit on a headlamp.
If the red light will illuminate reasonably well at around 50m I will not need to be able to use white light so it could be a red only headlamp.
Also although I have never re-flowed an led I wonder what sort of result I could expect if I re-flowed a red led onto say a 1000 lumen white led light ?
Failing the above a reasonably bright white light with red led/led”s as well ?
I know that the Nitecore NU10 has both a main white led & red but the white is only 160 lumens & the red is 13 lumens.

Especially the red LEDs cant be driven hard as blue LEDs
Their forward voltage is significant lower

If you would have a headlight with buck converter you could increase the sense resistor for lower current

XPE2 orange red driven at 1050mA on DTP star should give about 200 lumens
