Well, I do feel that Lite Panel is a bit over priced. But, the quality are relatively high. there are lots of LED lights available in the market. the problem to find one is good is not easy for most of the users. LED lights has to be built with good heat sink, good driver (ballast), high CRI and high TVLC, besides, it has to be good colour temperature.
at this moment, most of the cheap one is made in China by lots of non Film/TV/Video experienced technicians/companies. So the products can only be used for few times and the colour, light, CRI, TLVC deficiency, deal to the products is not made with the above requirements.
so I suggest you should be careful to buy this products online without consulting the sales engineers.
I starts dealing with high power LED for general lighting since 2004, simultaneously I also exporting China Made location light of PAR and Fresnel compact. I did not develop the America Market and I did not have any contact. since so many years, I tried to develop some LED light but due to the technical requirements above. It stopped me. In 2015, I re-start the LED for Film/TV/Video shooting. and the products soon will be launched. There will be 3 products, one of it is the LED 4 ft tube replacement to KINOFLO with 24V DC and supply with a Step Down transformer. Please let me know if you are interested. You can contact me by my email: info@illum-lite.com. (please note that the web site is under construction.)
BTW, please feel free to contact me for any technical details you would like to know. I shall try my best to explain.
