matrix0405 0 Report post Posted February 16, 2011 I have a new hamburger-type ceiling light and I think the cover is 'over frosted'. When I put up the cover, around 50% of the brightness is cut off and the room becomes not bright enough. So the cover is taken off to expose the bulb but the light becomes 'unsightly' or 'incomplete'. Anybody face the same problem and have a solutions? Like is there some way we can defrost the glass cover (with chemical or scrubbing etc?) Or can we drill some holes (likely will crack?) on the glass cover to allow more light through? Any good suggestions? TIA. Share this post Link to post Share on other sites

Don't quite understand WHY nowaday ppls still like filament bulbs which emit great amount of heat and give off "yellowish" light, of course it still contain some amount of "white light". Law of physics tells us that when pure yellow (combination of red & green)light shine on objects of different colors, have the following observation: - white, see as yellow, yellow light being reflected away. - black, see as black, yellow light being absorbed. - Green, see as green, red being absorbed, green reflected - Red, see as red, green being absorbed, red reflected. - Blue, see as black, yellow being absorbed, none reflected. so on so for. What I'm trying to say is that in "yellowish" light condition, one can't differtiate the "true" colors of objects! So when selecting colors in showrooms with yellowish light environment, watch out, don't be deceived. I have a new hamburger-type ceiling light and I think the cover is 'over frosted'.

(You can check with the lighting shop that you bought it from). If you have this option, you can try installing another tube inside so that when you switch on the light, both tubes will be lighted and it should help brighten up the room. Alternatively there is this super bright light tube - can't remember the brand, I think it's made by Hitachi if I'm not mistaken. A bit more costly, but brighter than the standard light tubes. You can't scrub off the "frost" or remove the opaqueness of the light covers otherwise you'll damage it, not to mention drilling holes on it!! Share this post Link to post Share on other sites
Topspin 1 Report post Posted March 24, 2011 (edited) I had the same problem in my previous house, the lightings came with the house. The opaque plastic cover is too thick so I just removed the cover, no choice but to live with the sight. In my present home, I made sure the cover is made of glass and it is just opaque enough to hide the wiring and ballast without cutting off too much light. Even so, in one room, I still find it too dark for reading with just a standard 32W round tube. So I just hooked up a standard bulb socket directly to the lamp electrical wires. I then screwed in a 20Watt compact fluorescent tube (from Ikea). I used cable tie to hold it in place. The space in between the circular tube and cover is just about enough to squeeze one compact tube energy saving bulb inside it...don't bother trying to put in two bulbs. So, each time I switch on the ceiling light, both the circular 32W tube and the 20 watt compact tube will light up. (don't use normal incandescent bulb as the heat generated may damage the circular tube and the electronics) Just make sure you know how to do the wiring safely if you wish to attempt this.
