This is white asbestos which is the less dangerous form. As long as you don’t saw or sand the stuff, producing asbestos dust, you should be ok.
My (late) mother used to warm the croissants on top of an asbestos simmer plate on the stove. But I will more probably die from her chip pan: she never replaced the fat for 20 years, when the level got low she just added new fat.
If I were to solder 4 nichia 119’s onto an VR21SP4 would they be spaced correctly for a Carclo quad or because of how the LED’s will center on the pads will the led to optic cone spacing be wrong?
Clemence, have you considered making 3x3 E21A MCPCBs? Would be expensive but compatible with 7070 optics (aside from low height) and producing a lot of high quality light.
Clemence, would taking pre-orders for future products in your store help with speeding up development time? If so, I would gladly pay ahead for some 3x3 E21A along with Carclo triple compatible e21a boards.
Just a thought. Excited for what your doing! Keep up the good work!
Total current is 4.9A, so 0.6125A per LED (two strings of four LEDs are in parallel, so there needs to be a bit a tolerance for the max current per LED). Generelly it's very low powered.
I bet quite a few people might be interested in this. The interest list for the lantern alrrady has over 2000 entries!
For lantern with no directional beam needed, I suggest 757 LEDs. Depending on the space available you can populate lots of them to get very high efficiency at much cheaper price. The options are.

NF2W757GV3F1:
- R95: 5000K
Note: $0,3/pc. Priced very close to Optisolis, CRI slightly higher than R9080 unlike Optisolis, they can be mixed freely

NF2L757GF1 (Optisolis):
It should be noted, for this purpose, that it’s max 2.34A (7*7135) per channel and that is with all solder bridges connected. The factory default will likely be even less:
You can add/remove the solder bridges to enable/disable current. He could even add more LEDs to reduce current per LED as long as it’s symmetrical.
I would be interested in a new board but only if it is E21A because the E21A comes has the famous 9080 2000k option that can mimic candle light. Since the other options only go down to 2700K, it doesn’t add much more to the stock 3000K to 5000K LH351D 90CRI, despite the Optisolis has superior color rendering.
