Yes there should realize the opportunity to RSS commentary, quite simply, CMS is another on the blog.

This is a very cool[no pun intended] idea. The source is in the ideal place, the center of the globe. The globe can be made of plastic, thus very durable. I have not yet seen an LED product with a heat issue at all let alone one close to that of an incandescent bulb. In a conventional incandescent bulb, the glass bulb itself is the radiator. Also the bulb can be offered with a variety of coatings much like today. I grant that intensity may be an issue, but I expect that that technology is much more advanced than any of us have any idea. The largest LED I am aware of is 1 watt ,but my information is old. I have been watching LED technology for some time, and I hope it will save us from the ghastly spectre of compact fluorescents. I would like to pre-order 10 000 units just like that other guy.

i see few problems with this design.

1) there are no single unit LEDs which can put out 60watts of light., single units 0.5 watts of light at most (currently).
2) LEDs are DC current, the AC to DC converter is not shown (they are rather large).
3) this LED would only cast light in a 160 degree spotlight cone, not 360 degrees "bubble" like a regular lightbulb. (see spuffler)

A "cluster" of 10 LEDs could solve 1& 3 problems
an LED light would operate at cool temperatures and could be made of clear polycarbonate plastic – unbreakable, recyclable, cheaper – better than glass bulbs.

Apparently you’ve never used an LED lamp to replace the incandescent. LEDs transmit light at a narrow angle. Currently marketed via WalMart, some LED lamps can never replace incandescents because the light from that particular LED design is not radiating outward from the bulb in a spherical manner – the arrangement of LEDs inside the WalMart product (Lights of America, if I recall, but I might be wrong) does not project light sideways nor towards the base of the lamp. So, all in all, we have NOT YET replaced the incandescent; no, not as of this post. CFLs also suffer from not starting when the whole lamp is cold; I refer to typical North American outdoor temperatures as found during winter months.

These are concepts – not actual product. What we’d like the world to be made up of rather than the crappy toaster you have smokin’ away in the kitchen and the knackered sofa bleeding its inards all over the living room floor. You know, the kinda place we all actually live in.

This LED appears to be just a design; all form and no function. Notice there are no photos of it actually emitting light. Any useful LED (>400 lumens) requires significant heat sinking. This design has zero surface area for heat sinking. Any significant LED used in this ‘Frog Design’ setup would burn out almost instantly were it given power to the diode.

Hi there,

can you please send me more info on the Frog-light.
And could you please respond to my email as i would like to get pricing on bulk order’s.
In range of 10,000 units.

As well what other product do you have in the lighting department.
A brochure would be great with details and info, and yet again pricing on 10,000 units.

Thank you
Johnny
