Emisar D4 optic change

I ordered a Emisar D4 with the stock optic but after watching some videos and reading reviews I think I would prefer the floody (frosted) optic.

Has anyone changed the optic in the D4, is it an easy process or will it require a complete dissemble / re-glue?

Also I have noticed the floody optic upgrade has been removed from the various options on Outdoor Store now.

There is no glue, though unscrewing the bezel sometimes requires a lot of force.
Unscrew, replace optic, screw back, done.

Okay great, do you know where you can get the optics from?

Here’s a link to Carclo’s list of distributors.

There’s also a phone number on that page for their UK office.

LEDSupply.com is a great source in the US, but international shipping is really expensive.

Really helpful thanks. I already have a Mouser account so can get them next day for cheap!

I bought a bunch of optics from MTNelectronics but they only have the frosted 10623, which I already have. However, LEDsupply has the even floodier 10624 frosted optic so I ordered from LEDsupply. Can’t wait to test it out.

One additional point … to make the optic fit in the newer D4’s when screws secure the MCPCB.

You need to cut off two of the legs to allow the new optic to fit. I used a small snub nose wire cutter but even a nail clipper might do the job.

I replaced the optic on my new D4Ti with a 10623. I like the results for the beam. My D4Ti is a Nichia 219C.

The ones without the screws are a problem because they tend to twist the heck out of the wires and why they probably added the screws.

I just received my 10624 from LEDsupply and simply used a wire cutter to pinch off two legs, which was super easy to do. Now I have an even floodier D4! Very nice!

Has anyone tried the narrower-than-stock 10621 optic from MTN? Since a quad is, by nature, somewhat floody, I thought I’d try the narrow optic. Have a few on the way from MTN so I’ll let ya’ll know. Beer

So does the floody optic reduce the light’s output if it’s frosted? I’m interested in more flood, but not reduced output.

I don’t think the frosted optic reduces the overall light output. But it will disperse it over a wider area so the light level in middle will be reduced.

I think it does reduce a bit. Even DC-Fix reduces lumens by about 3%, which is not detectable by the eyes. However, if you were to do a ceiling bounce with a floody optics, your measured lux will be significantly lower because it is spread out and not as much of the light reflects back to the sensor.
