Sofirn SP40...Better LED?

I decided to play around and take the SP40 apart and see what is what. Putting it back together i figured I’d leave the reflector out and wow, I like what I see! Pretty decent wall of light without a defined hot spot.

Ya see, I do a lot of new construction house painting (Cutting in and rolling) and a lot of times there is no electric so I rely heavily on a headlamp. Don’t like that hot spot glare. Sans the reflector the SP40 shines a smooth beam. Just don’t really like the tint and would like better CRI. Them similar colors start to be hard to distinguish with these older eyes. LOL

So, I guess my question is… what would the LED gurus on BLF recommend ?

The Samsung LH351D in 4000K from mtnelectronics would be a reasonable option.

Thanks. Does it already come on a board? Not sure if I know what I’m talking about. lol Where I can just de solder the round board and solder the other in? Sorry for the stupid questions. coming in this modding stuff on the ground floor.

You can buy it, a board, and their reflow soldering option.

This is my choice... will do mod in next week or so. great source

Does anyone know if the S2+ TIRs fit the SP40?

No, they’re a fair bit too tall. One of the first things I tried! I had to settle for a bit of DC-fix instead.

Thank you. Saved me some experimenting.

No. They are too wide, too tall and there’s not enough material to work if you were to sand it to fit.

I sanded one of these to fit, as they have more play room (6.09mm vs 4.71mm convoy). It does affect the optic/beam pattern but it’s not a donut hole or anything, just more light is dispersed to the sides. I had to leave out the glass lens. :weary:

Lightly scuffing up the lens to make it opaque or using milky dc fix would achieve similar results with less effort, going with a floodier emitter like LH351D also helps.

I am going to use DC Fix. Easier to go back and forth.

Much thanks everyone. Looks like I’ll be placing an order with mtnelectroninics. Now where is my soldering iron I last used ten years ago?
