Quoted from JethroP:Totally understand, but this is my hobby, I'm retired, and I enjoy it! Besides, like the fact I can make up 150 LED's for about the cost you spend to buy just 5. Isn't retirement great?!
Let's safely assume you value your time at zero dollars per hour (which is fine, you enjoy this as a hobby in retirement). The problem here is that you are inferring a 30 ratio of the cost of commercial bulbs to one of yours. So if your bulbs cost 5 cents, as you say, a similar commercial bulb is $1.50. That's no where remotely near true. In fact, having watched your video using straight LEDs out of a harbor freight lamp, the parts you are using are comparable to 1 LED bulbs that are available at COMET, for example, at $29 per 100, or roughly a 6 ratio.
I get it, and I'm not trying to dissuade you, but I LED games for customers all the time. The days of $200 or even $150 LED jobs are over (unless someone is overpaying for a premade "kit"). Even using the preferred SMDs over LEDs, I'm spending around $80 on an entire game (including backbox and GI), and if I need to use non-ghosting lamps in the inserts on certain titles, I'm barely over $100 in pure bulb costs.
