I read an extensive article about anodizing aluminum. It explained the honeycomb-like-physical properties of the nano-tubes that form during the process. This is what holds the dye that can give various colors. The article said white dye has an atomic structure too large to fit in the nano-tubes, so as they said you’ll never see a white anodized aluminum.
The article also went on to say that for similar reasons, colors don’t work well with Type III Military Grade Hard Anodize.
“It’s not a linear scale.
The stated outputs are the power level, which can be misleading. Throw distance follows an inverse square law, while perceived brightness tends to follow something like an inverse cube. So, there’s usually not much point having a mode between 50% and 100% power.
For example, let’s say it puts out 1000 lumens and does 50 kcd lux. Here are the resulting levels in more detail:
0.1% power: 1 lm, throws 14 m, brightness 10/100
1% power: 10 lm, throws 45 m, brightness 21/100
10% power: 100 lm, throws 141 m, brightness 46/100
35% power: 350 lm, throws 264 m, brightness 70/100
100% power: 1000 lm, throws 447 m, brightness 100/100
So, to a human eye, the 35% level actually looks like it’s 70% as bright as the 100% level, and it throws 59% as far. Does the mode spacing make more sense now?”
Setting the linear numbers in the firmware is not the same as the non-linear output. Which of course causes confusion until you come to grips with the fact that you’re dealing with 2 separate things.
How does one ask for a discount? Is there an entry on the checkout page for a discount code? It’s been awhile since I bought things from Simon and perhaps I missed it. Or is it requested by email?
You purchase the light , but you don’t pay .
and you leave a message on the order to have discount for blf member .
And then Simon re-adjust price and you pay
What you do is place your order right up to the point of clicking buy or pay or whatever it says but don’t put in any credit card info. That will generate an order number. Send Simon a message through the Ali message system (you’ll see the links on the left of the page). Give Simon your order number, tell him you are a BLF member and you would like him to adjust the BLF price (15% discount) this is also when you need to tell him if you want to pay through PayPal. He will adjust the price and then you either pay through the Ali system or ask him to send you a PayPal invoice. You can also just send him a payment using his PayPal address and reference the order number. If you go that route make sure you send him another message letting him know you paid and include the order number and any other info. It’s all a little unconventional but it works quite well in the end.
Edit: I see George summed it up pretty well in the post above. I tend to be a bit…wordy.
EditEdit: So wordy that I got my very first rude mark today. :zipper_mouth_face:
