I might sound like an ad for a certain light manufacturer but the adage that a light is the sum of its' parts is very true. I've seen "75 watt" HIDs that are woeful and easily outperformed by a good quality 50 watt system using high quality components. The situation is a bit different with lights because it's the output that people want. A 2000 watt toaster uses 2000 watts and no-one cares that it is so inefficient that it takes twice as long to make your brekky as the one that is maybe only 1500 watts but is more efficient. With inefficiency losses at 20% that's a lot of energy being tossed up in heat so the advantage of HID in terms of lumens/watt is actually lost.ĭomestic electrical appliances are rated on input. If ballasts were rated on output then there is the risk of overloading circuits. There are potential problems with the other way, too. Yes, the industry standard is misleading because people think they're getting lights that will give 75 watts output but in fact only give 60 watts. Whiter light than most halogens and much better colour rendering index (so you can see the colour difference between that kangaroo and the similar shaped bush). Just as a comparison the Fyrlyt will produce 5000 lumens with instant on and a pair costs $600 retail with discount prices down to $530. Nevertheless, that is a long time that you're driving without full light. It should be noted though, that these are enormous gains over the 40 seconds that these high output ballasts took only a few years ago. I don't know where these ballasts of yours fit in and I'll reserve judgement until I've seen and tested some.Ī 5 second warmup time is quite long compared to current technology which has claims as low as 1 second while good quality aftermarket are around 2-4 seconds to get to 80% (which looks like 100%). ![]() Using 80 lumens/watt this means that such a light will give a total of 4800 lumens. your typical 75 watt ballast uses 75 watts but only puts out 80% of this, i.e. For higher outputs, ballast losses through inefficiency are typically 20% for aftermarket although there are plenty that are much worse than that and only a few that are better. ![]() The more often quoted figure of 3200 lumens is with OEM bulbs but again is often used to inflate the supposed performance of the ballast or combination. For 35 watt ballasts that are measured by their output to bulbs this will produce a typical output of 2700 - 3000 lumens. can achieve around 90 lumens/watt while most Chinese aftermarket bulbs are in the 75-85 lumens/watt range. OEM quality bulbs & ballasts like Philips/Hella/Denso etc. The actual light output you get from an HID system depends on the combination of both bulb and ballast. However, ballasts with higher ratings (which came on to the scene later) were rated on their input as the clever marketers looked for an advantage. These were the first ballasts available for automotive use and this practice has become standard. So, although they consume around 42 watts their rating is 35 watts. 35 watt ballasts are rated on their output. This is because ballasts are rated in two ways. Only the biggest HID sellers in the US have had the kind of capacity and volume to make such an investment economic and much of their stuff is just rebranded, too.Īs for the quoted ratings, again your supplier seems to have broken with the industry standard practice which is highly misleading. This is most unusual, in fact an industry first for a retrofitter as far as I know (and I've been in the industry for around 5 years), given that it requires a significant investment in both tooling and in minimum production runs that the factory insists on in order to keep their costs under control. I understand that these 75 watt ballasts are specifically built to your supplier's specification. These are true 70 watts not the Chinese ones on EBay claiming to be 70 watts which are just re stickered 50 watt ballasts.
