Glare

Generally speaking, LED light bulbs are the replacement of incandescent and florescent bulbs and installed in their fixtures. The size of a LED bulb plays an important role to deliver comfort light. As you can see on the Fig-1 above, it is a same fixture but installed 3 different light bulbs to compare the degree of glare. The longer the bulb is, the worse the glare is. It is quite difficult to design a LED bulb with high lumen and small size, because that a LED bulb need certain volume to dissipate its heat. So, it becomes an Olympic game to push the envelope on reducing size and energy consumption of LED bulbs and increasing its lumen. XLEDIA developed several unique technologies to bring all of these together. XLEDIA were the first company launched 1520 lm with the exact size of an incandescent bulb (60x110mm or 2.4”x4.3”). It is the most compact size in this industry. Its compact size in the recessed fixture can significantly cut the light emitting into your eyes directly and reduce the glare.

Fig-2 is another sample that wrong sizes cause glare. Many fixtures were designed with the size of the original Edison bulb which was diameter 2.36”x length 4.33” (dia 60×110 mm). So, if you choose a replacement with larger sizes, the wrong size of LED bulbs may cause glare as shown in Fig-2.
