I must have spent the best part of a week looking up makes and watching all the videos out there but still empty handed. Looking for the following:
- comfortable headband
- low light setting (5 lumen?)
- high cri
- very warm white
diffused hotspot (50cm diameter at 30cm)
Use case is to read stuff in bed without risking divorce.
The closest I seem to have found is the Sofirn HS05 with LH351D and 2700K. But confused though by why the same seller has two listings, one for an HS05 in three temperatures and another “new HS05” in 5000K.
maybe a good suggestion if the OP is OK with 4000k or higher, but he asked for Warm (2700k), the LEDs fireflies offer are not what I would call Warm:
Emitter type:
SST20 10W 5000K NW
SST20 4000K FA3 CRI95
Nichia 219B 4000K SW40 D220 R9080
XPL Hi V3 1A Cool White (+$15.00)
XPL Hi V2 5A 4000K Neutral White (+$15.00)
definition of Warm:
“measured by Correlated Color Temperature, which assigns a value in degrees Kelvin to different Color Temperatures, from 5700K for cool white to 2700K for warm white, with 4500K being neutral. ”
Unfortunately there are not a lot of choices under 4000k with a high cri. The hs05 might work but they show a moonlight of 1 and the next level is 10 so you may not get exactly where you want. And I’m going to guess that it has a fairly tight spot. The sp40a claims a low of 5 but that could be off a little but in either direction. As to the different listings, I would guess when that headlight first came out that it was only available with the 5000k. When they added other options they created a different listing.
Can anyone even tell high/low CRI when just reading?
I use that LITOM horseshoe-shaped around-the-neck reading light. Super WW is almost amber, like 2200K, but it’s phosphor-converted, so you can still see red through blue.
That was my top choice for a while because of the beaded TIR, floodiness, etc but it seems that a lot of people had build issues with it. Not sure if that was a thing of the past. Thoughts? Since I fell down the rabbit hole I ended up with, almost exclusively, Convoys and [as Eek-A-Mouse sang] I like them all.
I think the HS05 is a perfectly fine choice!
If you’re not able to find a TIR that fits, you can try applying a window security film (like DC-fix) or Scotch tape to the lens.
It’ll diffuse the hotspot, and you could apply multiple layers for greater effect.
There will naturally be some output losses - but depending on your use case that may actually be desirable.
Hi, I may answer why there are two listings :D. One ships from USA, the other ships from China. The title can tell the difference.
Now 2700K HS05 is out of stock
You have to know size of HS05 reflector and their room.
Be carefull if you want try unscrew the silver ring holder to avoid scratchs
For my SP40 I used a tool for open watch back case that I already had
Convoy have 17mm Tir lens,but now store is closed.
Can’t guarantee they will fit or it may be necessary to file them to reduce the depth
