I wrote them an email asking for an explanation.
I am absolutely wired for sound and the color quality is lovely. I need to shut it down soon that I can hope to sleep again before March.
10/10, would buy this monstrosity again.
20181108 update: Having the desired effect. Great buy.
The design of this bulb is definitely outside the box. Most of today's LED bulbs are made to look as conventional as possible, hiding away the LED components under a frosted glass dome. This bulb doesn't to that. Instead the LEDs are arrayed on the outside of a hollow ceramic base with slots designed to facilitate superior airflow and cooling. This keeps the LED elements much cooler than in most other bulbs, improving efficiency. The lack of a frosted glass diffuser over the bulb also helps to maximize light output, leading to an amazing lumen per watt ratio of almost 130. These bulbs are a bit pricey, but the added efficiency more than pays for itself over the life of the bulb.
There are some downsides to these bulbs. As someone else pointed out, they're not certified and we have to trust in Sansi's honesty in reporting their specs. However, I can certainly attest to the brightness of these bulbs. Yes, they're made in China, but then so was my iPhone. The quality of this product speaks for itself. The lack of a frosted glass diffuser does result in harsher shadows from this bulb. The shadows are not as harsh as with a clear glass incandescent bulb, but they're noticeably sharp. I would not use these bulbs for direct lighting - in fact, the LEDs are painfully bright and should not be visible in use. These bulbs are best used for indirect lighting as in a torch light, or behind a diffuser or lamp shade. I would also note that the color rendering index is only 80. Although much better than some, it is a far cry from the 95+ CRI of some of the newest LED bulbs out there. Of course there is a trade-off between CRI and efficiency and unless one needs critically accurate color rendition, a CRI of 80 is adequate for most situations.
Time will tell how well these bulbs function over their lifespan. The reported 25,000 hour life is only half that of comparable LED bulbs, but the 5 year warrantee makes these bulbs an excellent gamble.
I just received these bulbs a few days ago so while I can't comment on longevity, I am otherwise very impressed. I did not measure the light from these with any instrumentation but to my eyes, both the 3000k color rating and the 3500 lumen ratings seem about right. The bulbs have a very solid feel and we have not experienced any flickering or humming from them. They are definitely bigger than a regular bulb (these are A21s not A19s) so make sure you pay attention to the specs and have room for them)
The light color is just a little cleaner looking than an incandescent or your standard "warm white" LED/CFL bulb-- noticeably more "pure" white but not so much that they would clash with 2700k bulbs on the other side of the room (need to see them side by side to really notice). I typically prefer more neutral white (3000k - 4000k) but my wife really likes the old fashioned yellower bulbs. These will do nicely to further my plot of slowly transitioning without her noticing. =)
Other than my cell phone, I don't have anything to test the 3500 lumen claim but I will say these are definitely very bright bulbs. They are noticeably brighter than the 42 watt (150 watt equivalent) 2600 lumen CFL bulbs they are replacing and I think the slightly higher color temp as well as the relatively higher CRI lend to their effectiveness as well.
can't comment on this yet as I haven't tested them with a dimmer switch. will update if I get the chance.
It's worth paying attention to the rated 270 degree light angle. the tops of the bulbs are dedicated to their electronics and heat distribution so there is a noticeable darker area directly over the top of the bulb. We have a table lamp that has sort of a weird housing inside and bulbs are mounted horizontally (so they're pointed at the side of the lamp shade as opposed to at the ceiling). There was a noticeable dark circle on the lamp shade and while we were happy just rotating the lamp so that part is facing the corner, for others, this might be distracting. However, in our other normal table lamp where the bulb seats normally and faces up, this wasn't a problem. So I would say avoid using these in housings where the end of the bulb will be pointing directly at where you need the most light. Mounted vertically in a table/floor lamp or horizontally in a high up wall fixture would seem to be the among the better situations for them. They'd also be GREAT for exterior fixtures, if you're lucky enough to have ones big enough to fit them. I was able to screw the bulb into mine and turn it on...the light looked amazing and really lit up the exterior of my house but the bulb was mashed in there and it just wouldn't have worked long term.
They do seem to produce a lot of heat for LEDs but IMHO, not to a problematic degree. The ends of them (where they have the ceramic heat sinks) get hot enough that even a 1/2 second tap with your finger tip is uncomfortable. The manufacturer does not recommend using them in fully enclosed fixtures and I can see why: unless such a fixture was located in a walk-in freezer, I would say it wouldn't be a good idea: reduced bulb life-span at best, fire hazard at worst.
So to sum up this long-winded review: they won't work everywhere for everybody but in the right situations, these are EXCELLENT lights!

Huge improvement over the standard LED bulbs I had in there before. Pictures don't quite do it justice, the difference is more substantial in person. Very pleased
These are the only high output led bulbs I've purchased so I can't compare them to others on the market but I can tell you they are far brighter than a standard led bulb
As I said I just installed them today so I can't speak for the longevity of these bulbs, but if something goes wrong I'll be sure to update my review
UPDATE-MARCH 7, 2020:
Still working great, went through -40°C weather no problem. Turns on instantly at full brightness no delay. Very happy with the purchase. Will update if any issues arise.
These are slightly larger than a standard bulb, so keep the dimensions in mind when planning your purchase.
The cost is a little high, but it's a unique product without significant competition. It also delivers on its promises. I would happily recommend.
