I am saying this because some lights bought from ebay or our north american distributors are old stock from them that couldnt be sold.
Anyways the point is that the phospor blend bug has been removed and even our waterproof housing fixture is being removed from the 400w series due to the concerns that the Kelving temperature reached after a long period of activity of the lighting system.
You should stick with the IP67 specification. One of the good uses for the induction lamp was for keeping outdoor sports fields green. What I would suggest doing is making a new heat sink on the top of the unit and directly affixing the unit to that.

I never purchased any lamps from your company, I sent off an e-mail to the company with a new phosphor blend that I was giving out for free because I wanted to see induction lighting gain a better edge versus fluorescents.

I have to say, however, that the lights still lack overall in photon flux emissions. If only you could make those tubes of a smaller diameter, and perhaps increase the tube pressure or harvest the mercury emission lines better. Maybe redo the entire tube and use aluminosilicate instead of borosilicate glass?
