A peek review with our next generation World Lamp

We are making our next generation World Lamp shell. What shows in this photo is a prototype of 2.5mm coroplast, the real deal will be made with 4mm coroplast, which is much stronger than existing lamp shell.
We moved its opening to top of lamp, and use tab insert instead of snap lock to latch the cover pan.
Everything else remain the same, you still get a nice 30 watt LED core to shine through exactly the same dual lamp windows. The only thing that's going to change is color. Which color should we pick?

New Packaging of World Lamp

Our World Lamps have been our best selling item, but it had been always packed in 4 lamps package. The long box packs 4 lamp shells, and 4 smaller boxes hold one light unit each. Then the whole package is shrink wrapped in thick plastic cover to be water repelled. This is nice but anyone buys World lamp have to get 4; no change. Package come in just 8 lbs.

 Recently we found USPS provides this 37" triangle shipping tube for free if you ship priority. So we decided that would help our business to provide some flexibility. We split the box of 4 lamps into two priority shipping tubes, and our customer now can order 2 lamps at almost half of price of 4 lamp pack.
The 2 lamp pack come in under 4 lbs.

Mount Easy LED module to wood frame

The main enemy for high power LED is heat. Our special design quickly dissipates heat from tiny LED chip to large area metal mounting plate; but the end game is still to spread heat out of this module to its surrounding, air in most cases.

If the application is to attach LED module to metal lamp case, then heat dissipation won't be a problem at all. So is to set it by itself that both sides of plate exposed to free air.

However, it's common desire that we want to attach this module to wood frame, which is easy mounting. The bad thing about it is that: Wood dissipates heat slowly, by attaching one side of LED module plate to wood, it's like cover 50% of heat sink area to stop heat transfer to air. That's bad and what can we do if we have to?

     Keep Air Flow
Below is an example how I attach our module to wood frame. I use screw nuts as spacer to keep air still get in touch with both sides of metal plate. Also it would be wise to mount the module to an airy location to keep cool. The result is good enough to sustain heat dissipation.
