  • Chip-on-board LEDs deliver high lumen output
  • How does anyone build a product around these when new versions come so quick and older versions are quickly discontinued? Also have had issues where two different models that say they have the same Color Temperature but look different in application due to different/improved the CRI or increased lm . So a high volume customer installs a bunch of these in some application, experiences some failures but the replacements look different due to either the CRI or lm output. So if they didn't overbuy for expected failures... A mess. Would understand if these were something like 5yr periods (but not even... a hotel lobby or cruise ship hallway) but even at 2yr marks they are out of luck unless someplace has extra and from the same bin. This is not an improvement for general lighting at all.

  • They're still selling incandescent flashlights?
  • LOL you joke BUT... Northern cities when first converting to LED traffic lights had an issue when the snows came (obviously doing the incandescent switch in the warmer months. When show accumulated on the fronts of the traffic lights... because the LED versions ran so much cooler... they didn't melt away the snow. Could still tell what was going on at night but during the day... LOLzzz

  • They can make LED light sources just as "adjustable" but requires more optical elements. Actual lenses over just moving the incandescent bulb in relation to the focus of a reflector. AND be sure LED versions are out there, just cost more than most are willing to pay so many retail sellers don't even bother to carry/show.

  • Tesla backlash shows misunderstanding of reality
  • After re-reading, seems I missed the point. Better example. Yes the hardware is there, do you expect them to use a different processor or PCB? You have a home computer but doubt that you grouse that every software package that can run on it isn't there for free (or rather for the cost of the machine). For a scope... sure there may be some advanced functions on one model that is materially the same as another but those development costs (of the advance functions) wern't free. So either everyone is asked to cover the costs, a bargain for those who want the features or there is some skewing hopefully putting the onus on to those that want the features. Personally would feel more offended by being asked to carry some of the costs of the advanced features as a "base" model buyer. If not needing the advanced features, why should any of their development costs be shifted to me?

  • Tesla backlash shows misunderstanding of reality
  • This is one aspect for sure. Like with DX and SX designated Intel Processors. Sure when they needed more of the SX versions they may have taken perfectly good DX's and hobbled them but the customer did get what they paid for.

  • Tesla backlash shows misunderstanding of reality
  • It is curious, when considering how much engineers hate the been counters and markers poking their noses in, then try to be marketers. Sometimes you got to move product to get costs lower, not everyone will pay top dollar but some will pay a lower cost. If the MFGR wants to take a loss (or _less_) on some to make those volume numbers... that's their biz. Sometimes this is in the form of reduced functionality, sometimes this is in the form of another market getting a different price point (gray goods). For example, in automobiles, the "Premium Option" package doesn't cost what is listed as the cost in materials (plus margin)... It is way cheaper and why that is the ideal up sell. Would be interesting for products to have a "price with no warranty or post sale support" option. More features mean more failure points and more features (can) lead to more post sales calls for support. When was the last time you paid for support? (looking at you Microsoft!)

  • Repugnantated Michael, So expected warranty costs on the accounting side should assume everyone uses all aspects to its potential max? What is your opinion of the sort of person that buys light duty equipment, destroys it doing heavy duty work then returns saying "Golly, only used the wrench/strap/whateves for a little whateves... and it broke. Never mind the 4' breaker bar we wuz usin'. GIMME A NEW ONE IT'S UNDER WARRANTY!!" For some things this doesn't make sense, but a car... there is a reason if you are SCCA racing you many not expect to have full warranty coverage. (again to be extreme) No the battery isn't that extreme but expect they counted the beans on total cycles and expected failure rates for discharge levels... sure also saw a way to make a few more bucks... but don't expect it is "pure profit." Repugnant... LOL There are a MANY things far and above, let's not make all words loose their value/impact. PLEASE!

  • Tesla backlash shows misunderstanding of reality
  • Repugnatated Scott... As some sort of an engineer... do you think a battery continuously used further into depletion would have a higher or lower failure rate? If a higher failure rate is reasonable, then that would impact warranty costs, possibly... yes? If warranty costs are higher for a battery routinely into a deeper depletion zone, would you expect the manufacturer to bake that higher cost in? Would you feel better if everyone was charged the higher cost, even if they don't use the battery deep into the depletion zone? ¯\_(ツ)_/¯

  • Beware the TO-220
  • Seriously. "THEY DON"T MAKE IT LIKE THEY USED TO" while working in every-way not to spend a dollar. Yawn, thank goodness. Let's move on.

  • Merging power and data: good, bad, or both?
  • One is a concept the other implementation... kind of unfair to knock the concept based on some MFGRs crappy implementation. Lets talk about CFLs and LED lamps... in a few years. The concept isn't bad, it's the products. Though, am 100% sure personally, wouldn't pony up the cost of a LED lamp that was designed to last the MFGR's claims.
